Short answer: probably not — and the bag of frozen peas may be slowing you down.
It’s the first thing almost everyone reaches for. You feel something go in your calf, you limp home, and within twenty minutes there’s ice strapped to your leg because that’s what you’ve always been told to do.
RICE — rest, ice, compression, elevation — has been the standard advice since 1978. The problem is that Dr Gabe Mirkin, the doctor who coined it, has since publicly walked back the ice part. The evidence has moved on considerably. Ice is still worth knowing about. It just isn’t doing what most runners think it’s doing.
What’s actually happening in there
When you injure a muscle, tendon or ligament, your body starts a repair process straight away. Cells at the injury site die off and release chemicals that trigger bleeding for a few hours, then a clot forms, then inflammation kicks in — a cascade of chemical activity that clears out the debris and signals the next stage of healing to begin.
Heat, redness, swelling, pain, and not being able to use the leg properly: those are the signs of inflammation, and they usually run for around three days.
Here’s the part that changes things. That inflammation isn’t the injury. It’s the repair. Ice and anti-inflammatory medication both suppress it, and the evidence suggests that suppressing it hinders the response and delays muscle repair. You’re not treating the problem — you’re interrupting the solution.
Worth being straight with you about the strength of that evidence: it’s stronger for anti-inflammatory drugs than it is for ice, where much of the work is in animal and laboratory studies rather than large trials in runners. The direction of travel is clear enough, but nobody should be claiming certainty here.
So why does ice feel like it helps?
Because it numbs things, and numb is a relief when you’re sore. That’s a real benefit and I’m not going to pretend otherwise. If you’re in enough pain that you can’t sleep, ice it for ten minutes and take the edge off.
Just be clear about what you’ve bought: short-term comfort, not faster healing.
What to do instead
The framework that’s replaced RICE is PEACE & LOVE. It’s a bit of a mouthful, but it splits neatly into the first few days and everything after.
PEACE — the first 48 to 72 hours
- Protect — avoid the activities that clearly increase your pain. Protect, not immobilise.
- Elevate — get the limb up where you reasonably can.
- Avoid anti-inflammatories — and ice, for the same reason. Let the process run.
- Compress — mostly another form of protection. Comfortable, not tight.
- Educate — understand that your body heals this on its own. Most paid interventions in that first window cost money and add little.
LOVE — from a few days on
- Load — start reintroducing movement. Let pain guide you rather than stop you.
- Optimism — be confident in your body. Most injuries heal well on their own, and expecting to recover genuinely affects whether you do.
- Vascularisation — light cardio to get blood moving around the healing tissue. Bike, swim, walk.
- Exercise — rebuild mobility, strength and control properly, with a plan.
How long should this take?
Longer than most runners expect, and that’s normal rather than alarming. A mild muscle strain is often sorted inside a fortnight. A moderate one can take up to three months. Tendon problems tend to sit somewhere between three weeks and six months depending on what’s going on.
Those ranges aren’t a warning. They’re there so you stop panicking on day four when it still hurts, and so you stop testing it every morning to see if it’s gone.
The bit people get wrong at the end
The riskiest moment isn’t the injury. It’s the fortnight after you start feeling better, when the rehab quietly stops because the pain has. Tissue keeps remodelling for weeks — sometimes months — after it stops hurting, and that gap between feeling fine and being robust is where most re-injuries happen.
Keep loading it. Keep the exercises going a bit longer than feels necessary.
When to get someone to look at it
Take 24 to 48 hours off, rest it, and see how it settles. Most things do. If the pain hasn’t started to settle after that, or it keeps coming back to the same spot every time you build up your mileage, that’s the point to get it assessed properly rather than guessing.
And worth saying plainly, because it’s the fear underneath most of these questions: pain is very rarely a measure of damage. It usually means an area has become sensitive, or your body is being protective to get your attention. It’s rare to have done anything lasting to yourself with a running injury.
