Horse Sprains & Strains: What to Know

First published September 2020 · Revised 2026Written by Kara Gardiner, Nzymes Equine Specialist

A hole in the pasture, a bad landing, one twist too many. Now he's off in his gaits and you're trying to work out how bad it is. Here's how to read it, and what helps.

First, which one is it

A sprain is the joint. A strain is the muscle.

With horses, the difference is simple to say and hard to see from the outside: a sprain is an injury to the ligaments in a joint, and a strain is an injury to a muscle or to the tendon of the muscle around the joint. Both are painful, and either can leave a horse off in his gaits or visibly lame.

The common causes are the ones every horse owner knows: stepping in an unseen hole, falling, twisting, repetitive strenuous work, or trauma to the joint. Any of these can push the leg joint out of its normal range, tearing or stretching the ligaments, muscles, and tendons as it goes.

What to check for

You will know a lot just by looking at your horse. Some cases need the vet; others are minor and settle with home care. Use your best judgment: a vet can confirm whether it's a sprain, a strain, or lameness from something different, like a hoof abscess. The sooner you start dealing with the pain and swelling, the sooner your horse is on the mend.

Working through it

Cold first. Heat later. Rest most of all.

First · while swollen
Cold hosing

Run water from a garden hose over the injury for 20 minutes, twice a day, until the swelling subsides. If he's uneasy about it, start low on the leg and work your way up. Below freezing? A 20-minute ice pack does the same job.

Later · once swelling is gone
Heat & massage

Several days to a week in, warm moist heat for 20 minutes once or twice a day relieves pain and brings blood flow to the injury. Light hand pressure in long strokes down the full leg helps circulation and can reduce scar tissue. The goal with any injury is to bring back the full range of motion, so massage, along with light exercise, helps the mending along.

If he's shod
Therapeutic shoes

Your farrier can recommend a removable set, or apply them semi-permanently. Not suited to every sprain or strain, but they can absorb ground impact while the leg mends.

Most of all
Rest

Give him real time off. Getting back into work too quickly is how a mending leg gets re-injured, and the second rehab is always harder than the first.

The nutrition underneath it all

Given the right resources, the body repairs itself.

We've promoted a holistic nutritional approach to horse health for over 25 years, and it's a view more and more nutrition-conscious veterinarians, breeders, trainers, and owners share: given the proper nutritional resources, a horse's body has amazing restorative powers. It can repair faster, fight infection more readily, and keep its natural defenses strong.

Questions horse owners ask
What's the difference between a sprain and a strain?

A sprain is an injury to the ligaments in a joint. A strain is an injury to a muscle, or to the tendon of the muscle around the joint. Both are painful, and either can leave a horse off in his gaits or visibly lame.

Do I need the vet for a sprain or strain?

Some cases need the vet; others are minor and settle with home care. Use your best judgment. A vet can confirm whether it's a sprain, a strain, or lameness from something different, like a hoof abscess.

How does cold hosing work?

Run water from a garden hose over the injured area for 20 minutes, twice a day, until the swelling subsides. If your horse is uneasy, start low on the leg and work your way up. In freezing weather, a 20-minute ice pack does the same job.

When can heat be used?

Not right away. Wait until the swelling is fully worked out and the horse is several days to a week into mending. Then warm, moist heat for 20 minutes, once or twice a day, helps relieve pain and increase blood flow as rehab begins.

Why double the Granules after an injury?

Doubling the daily amount for the first 2 weeks front-loads nutritional support while the body has its biggest repair job to do. Some injuries take longer and may need continued support; two weeks is a good judgment period.

Not sure how bad it is?

Describe the limp to someone who's knelt next to one.
