“Should I use heat or ice for my injury?”

This is one of the most common questions I hear from clients of all ages, and seems to create a lot of confusion. When you’ve pulled a muscle or picked up a niggling injury, it’s easy to reach for whatever feels comforting in the moment, and honestly, that’s completely understandable.

The problem is that using the wrong one can actually slow your recovery or make symptoms worse. Heat and cold do very different jobs in the body, and knowing when to use each can make a big difference to pain levels, healing time, and how confident you feel moving again.

In this blog, I’ll break things down in simple terms. We’ll look at what’s really happening when you “pull” a muscle, when ice is the better choice, when heat is more helpful, and how compression fits into recovery – so you can care for injuries properly, recover more effectively, and reduce the risk of them coming back.

What happens when you “pull” a muscle?

When people say they’ve “pulled” a muscle, what they’re usually referring to is a muscle strain. That sounds technical, but the idea is actually quite simple.

A muscle strain happens when muscle fibres are stretched further than they’re ready for, or they’re asked to work harder than they can cope with at that moment. This can cause tiny tears in the muscle tissue, which is what leads to pain and discomfort.

This kind of injury can happen for lots of reasons, including:

• A sudden or awkward movement
• Lifting something heavier than expected
• Sprinting or changing direction quickly
• Training when you’re already tired or tight
• Not warming up properly

When a muscle is strained, your body reacts more or less instantly. You might notice:

• Pain or tenderness in the area
• Swelling or a “puffy” feeling
• Tightness or stiffness
• Reduced strength or range of movement

It’s worth knowing that not all muscle pulls are the same. Some are very mild and settle quickly, while others need more careful management. How you treat the injury in the early stages plays a big role in how fast you recover, and whether that same problem will continue to haunt you and return again.

Cold Compression: When and why to use it

Cold therapy is usually the best place to start when a muscle injury is fresh. If something has just happened and the area feels sore, swollen, or warm, cold is often your friend.

What cold therapy does:

When you apply cold to an injured area, it:

• Helps reduce swelling and inflammation
• Numbs pain by slowing down nerve signals
• Limits excessive blood flow to the area in the early stages

In simple terms, cold helps to calm things down while your body starts the healing process.

When cold compression works best

Cold compression is most useful in the first 24–72 hours after an injury, especially if:

• The injury came on suddenly
• There is visible swelling
• The area feels warm or inflamed
• Movement is painful straight away

This is where compression comes in. Using a cold pack with gentle compression helps control swelling more effectively than ice alone and can make the area feel more supported and comfortable.

How to Use Cold Compression Safely

• Apply a cold pack or cold compression wrap for 10–20 minutes
• Use it 2–3 times per day
• Always place a layer (like a towel) between the cold pack and your skin
• Allow the skin to return to normal temperature between applications

Common mistakes to avoid with cold compression

• Leaving ice on for too long
• Applying ice directly to the skin
• Using cold on long-standing stiffness rather than a new injury
• Continuing to ice for weeks when swelling has already settled

Cold is most helpful early on, but it’s not meant to be a long-term solution for every ache and pain.

Hot Compression: When and why to use it

Heat often feels comforting, which is why many people reach for it straight away. But heat works very differently to ice, and it’s most effective later in the recovery process, not at the very start of an injury.

What heat therapy does:

• Increases blood flow to the area
• Helps muscles relax
• Reduces feelings of stiffness and tightness

You can think of heat as helping muscles loosen up and move more easily, rather than calming inflammation.

When heat compression is most helpful

• The initial swelling has gone down
• The injury feels tight or stiff rather than swollen
• Pain is lingering but no longer sharp
• You’re preparing the area for gentle movement or exercise

This often applies to injuries that are a few days old, or to long-standing muscle tightness that hasn’t come from a sudden strain.

How to use heat safely

• Use a heat pack or warm compress for 15–20 minutes
• Make sure the heat feels warm, not hot
• Use heat before movement or stretching if advised

Common mistakes to avoid

• Using heat straight after pulling a muscle
• Applying heat to an area that’s still swollen or warm
• Falling asleep with a heat pack on
• Using heat to “push through” pain

If a muscle is still inflamed, heat can increase swelling and slow healing. That’s why timing really matters.

Cold vs Heat: A simple decision guide

If you’re ever unsure whether to use heat or cold, a quick check-in with your symptoms can usually point you in the right direction. Rather than guessing, think about what the area feels like right now.

Here’s a simple guide to help you decide:

As a general rule, cold calms things down, and heat loosens things up.

Where does compression fit into this?

One of the questions I get asked all the time is “will a compression sleeve actually help?”.

The short answer is yes – when it’s used for the right reason.

Compression simply means applying gentle, even pressure around an area. This can help support the tissue, manage swelling, and make an injury feel more secure, especially in the early stages of recovery or when you’re starting to move again.

Compression sleeves or wraps can:

• Help limit swelling after a muscle strain
• Provide light support to injured tissue
• Reduce that heavy or achy feeling around a sore muscle
• Improve confidence when returning to movement or exercise

For many people, compression also offers a sense of reassurance. Feeling supported can make it easier to move naturally, rather than guarding or tensing up around an injury.

When is a compression sleeve most useful?

A compression sleeve may be helpful:

• In the early stages, alongside cold therapy, to help manage swelling
• During the transition back to activity, when an area still feels vulnerable
• For longer days on your feet or during light training while recovering

That said, compression isn’t a cure on its own. It supports recovery but it doesn’t replace it.

A word of caution on compression:

Compression should never be tight or restrictive. If you notice:

• Tingling
• Numbness
• Increased pain
• Skin colour changes

Then the compression is too strong and should be loosened or removed.

Used correctly, compression can be a helpful tool. Used incorrectly, it can mask symptoms and delay proper recovery which is why timing and guidance really matter.

Why massage therapy matters in recovery

Heat, cold, and compression can all play a helpful role in managing a muscle injury, but they work best as part of a bigger picture, not on their own.

When a muscle is injured, the body often responds by tightening up around the area to protect it. This can lead to:

• Ongoing tightness
• Reduced movement
• Other muscles working harder to compensate

Over time, that protective tension can slow recovery or even lead to new aches and pains elsewhere.

Massage therapy helps by:

• Improving blood flow to support healing
• Reducing unnecessary muscle tension
• Encouraging better movement patterns
• Helping the body relax out of that “protective” state

One of the biggest benefits of hands-on treatment is that it allows for individual assessment. Not all injuries should be treated the same way, even if they feel similar. Understanding where the strain is, how your body is compensating, and what stage of healing you’re in makes a huge difference to recovery. If you’re looking for support tailored to your needs, my Sports Massage treatments are designed to speed recovery and prevent repeat injuries.

Massage isn’t about forcing change, it’s about giving the body the right support at the right time, so healing can happen more naturally and efficiently.

Preventing repeat injuries

One of the most frustrating things about muscle injuries isn’t the pain – it’s when the same problem keeps coming back with a vengence. Very often, repeat injuries happen not because the muscle is weak, but because it never fully recovered or the underlying cause wasn’t addressed.

A few simple habits can make a big difference:

Warm up properly – Muscles respond better when they’re prepared for movement. A short, purposeful warm-up is far more effective than jumping straight into activity.

Respect recovery time – Pain settling doesn’t always mean healing is complete. Returning too quickly can leave tissue vulnerable to re-injury.

Maintain mobility and flexibility – Tight or restricted areas are more likely to overload during movement. Regular mobility work helps spread load more evenly through the body.

Pay attention to early warning signs – Persistent tightness, discomfort, or reduced movement are often signals worth listening to – not pushing through.

Get support when needed – Regular maintenance treatment can help identify problem areas early, improve movement quality, and reduce the chance of small issues turning into bigger injuries.

Looking after your body consistently is usually far more effective than dealing with injuries only when they become painful.

Final thoughts…

Knowing when to use heat, cold, and compression can make a real difference to how quickly and comfortably you recover from a muscle injury. When you understand what your body needs at each stage, you reduce pain, support proper healing, and lower the risk of the problem returning. If you need assistance understanding your injuries, I can give you personalised advice.

Pulled muscles and niggling injuries are common, but they don’t have to become ongoing issues. With the right early care and sensible progression back to activity, most injuries recover well and allow you to move confidently again.

We all have scars. For some, they’re a small reminder of a past injury like a cut from a fall that healed quickly. For others, scars might be tied to more significant events like surgery or medical treatment, and can continue to affect how the body feels and moves long after the skin has healed. While scars are a normal part of the healing process, they don’t always recover well and for some people may remain tight, sensitive, painful, or even restrictive – these are what are known as adhesions.

Earlier this year, I introduced the ASA M8 laser system into my clinic, making Callum Wood Sports Massage the only clinic in Sussex currently offering this level of advanced photobiomodulation technology. Since then, it’s been receiving excellent feedback from clients, and it’s quickly become an essential and valuable part of the work I do with my clients. As with any advanced technology, I’m only just beginning to explore its full potential which is why I want to take a closer look at how it may support scar tissue healing through a documented case study.

Photobiomodulation itself isn’t new. It’s been used in medical and rehabilitation settings for many years, supported by a growing body of research around tissue healing and inflammation management. What is new for me is taking a more focused look at its application for treating scar tissue, and doing so in a transparent way.

In this blog, we’ll explain how photobiomodulation works in simple terms and introduce a free laser therapy giveaway!

What is Photobiomodulation?

Photobiomodulation (PBM) is a type of laser therapy that uses specific colours of light – usually red and near-infrared – to help the body heal itself. The light isn’t hot and doesn’t burn or damage tissue. Instead, it gently passes through the skin and is absorbed by the cells underneath.

Inside each cell are structures called mitochondria, often described as the “power houses” of the cell. When these mitochondria absorb laser light, they become more efficient at producing energy (called Adenosine Triphosphate ATP). At the same time, the light helps calm down excessive inflammation and improves blood flow in the area being treated. All of this creates better conditions for repair and regeneration.

Essentially, what this means is photobiomodulation gives injured or restricted tissue more energy, better circulation, and a calmer healing environment, allowing the body to do what it’s already trying to do, but more effectively.

This is particularly relevant for scar tissue. Scars are not just changes on the surface of the skin; they often involve altered collagen structure, reduced circulation, and lingering low-grade inflammation beneath the surface. PBM has been shown to influence the behaviour of fibroblasts (the cells responsible for producing collagen), support more organised tissue remodeling, and reduce excessive inflammatory responses which are all factors that can influence how a scar feels, moves, and adapts over time.

When working with different types of scar tissue in the clinic, particularly keloid scars, photobiomodulation has shown potential to reduce redness, itching, and stinging, which are common symptoms with this type of scarring. In some cases, the thickness of the scar may also reduce over time.

In my clinic I use the ASA M8 laser system, which delivers red and near-infrared light at carefully controlled doses. This allows me to work with both surface-level scars and deeper tissue changes, without heat or discomfort. Like most therapeutic tools, the effectiveness of PBM depends on how it’s applied including wavelength, dosage, and treatment frequency – which is why it’s important to approach scar treatment in a considered, evidence-informed way.

What does this look like in practice?

Photobiomodulation has been widely studied for wound healing and scar management, with professional case studies documenting improvements in pain, tissue quality, and scar appearance. One example is a systematic review and meta-analysis that looked at how low-level laser therapy affects skin wounds in multiple clinical trials. This analysis included data from hundreds of wounds including surgical scars, burns, ulcers, and graft donor sites, to compare outcomes between laser-treated groups and those receiving standard care.

Overall, the findings showed that wounds treated with low-level laser therapy healed faster and reduced in size more than those in control groups, with statistically significant improvements in complete healing rates. Pain levels were also lower in the laser-treated groups, suggesting real benefits in both tissue repair and comfort. While this research isn’t specific to every type of scar, it offers a practical clinical example of how controlled light-based therapy can support the body’s natural healing processes in real patients.
