Old Ankle Sprain That Still Feels Stiff

You rolled your ankle months ago.

The swelling went, the bruising faded, and you got on with things. But it still feels stiff first thing, aches after a long day, and you don’t quite trust it on uneven ground.

This is extremely common, and it’s not something you have to accept. It’s also the point where heat becomes appropriate, unlike in the first few days.

Why it lingers

Most people rest an ankle sprain until the pain settles and then return to normal without rehabilitating it. Three things are usually left behind:

• Stiffness in the joint, particularly the movement of bringing the toes up towards the shin. A stiff Achilles often goes with it.
• Weakness in the calf and the muscles on the outside of the ankle. See also calf cramps at night.
• Poor balance sense. Ligaments carry position sensors, and a sprain disrupts them. That’s the “doesn’t feel steady” sensation, and it’s why a first sprain makes a second more likely.

All three respond to training, even months or years later. A limp that lasts also changes how you load the foot, which is one route into heel pain.

Heat, then work

Cold was for the first 48–72 hours. That’s long past. Now warmth before exercise is the useful move, especially first thing in the morning. That order is the point: heat is the warm-up, not the treatment.

1. Wrap the pad loosely around the ankle, cover on, lowest setting, 10–15 minutes. Skin here sits close to bone, so check it afterwards.
2. Then the exercises below.
3. If the ankle swells after a big day, cold that evening is still reasonable. See hot or cold compress for swelling.

See the 48–72 hour rule for why the timing flips, and heat or ice: a physio’s decision guide for the general version.

Four things to work on

1. Range. Ankle circles, and spelling the alphabet with your big toe. Two minutes.
2. Knee-to-wall. Foot flat, knee bends forward towards the wall without the heel lifting. Compare sides; the injured one is usually stiffer. 10 reps, working to match the other side.
3. Calf raises. Rise onto your toes and lower slowly. Build to 20–25 on the injured leg alone. This is the strength piece and the one most people skip.
4. Single-leg balance. Stand on the injured leg for 30 seconds. Progress to eyes closed, or standing on a cushion. This retrains the position sense that prevents the next sprain.

Most days for six to eight weeks. Balance work in particular has good evidence for reducing repeat sprains. Expect some soreness as you build up: DOMS, heat or ice?

See a doctor or physio if…

• The ankle gives way, or you’ve sprained it repeatedly
• It locks, clicks painfully, or catches
• There’s tenderness directly on bone, which can indicate a missed fracture
• It swells regularly with ordinary activity
• You have numbness or pins and needles in the foot. If so, keep heat off that area: who should not use a heating pad.
• Pain is no better after six to eight weeks of consistent work

An ankle that still isn’t right months later is worth one assessment. Persistent symptoms after a sprain sometimes point to something the original injury masked. On stiff joints generally: heating pad for knee and joint pain.
