Why is my horse's graze crusty and sore?

Overview
A graze can look crusty and feel a bit sore while it’s healing, especially in the first few days. It can also become crusty if it’s been rubbed, kept damp, or irritated by mud, flies or bedding. If the area is getting more painful, more swollen, or starts to ooze, it’s worth keeping a closer eye on it.
Things To Check
1. Check when you first noticed the crusting and whether it’s changing day by day.
2. Look for redness, heat, swelling, discharge, smell or a wet-looking scab.
3. See whether the horse is rubbing the area on a fence, rug, stable wall or tack.
4. Check if mud, wet bedding or sweat is keeping the graze damp.
5. Notice whether the horse is sensitive when you touch around the area.
6. Look for swelling extending beyond the graze, especially on a leg.
7. Check whether flies are bothering the area, particularly in warmer weather.
Common Causes
The most common reason is normal healing. As a graze dries, it can form a crust or scab and feel a little tender.
Rubbing or repeated movement can make it look more sore and keep the surface from settling. This is common on legs, shoulders and girth areas.
Damp, mud, sweat or dirty bedding can soften the crust and irritate the skin underneath, which can make the area look worse.
Sometimes a graze has become mildly infected or has a bit of trapped debris in it. That can cause extra soreness, heat or discharge.
What To Do
Keep the area clean and dry, and check it once or twice a day so you can spot changes early. If it’s on a leg, try to reduce mud contact and keep the stable or turnout area as clean as you can.
Avoid picking at the crust unless your vet has advised otherwise, because that can delay healing and make the skin more irritated. If the horse is rubbing the area, look for the reason and reduce friction where possible.
If the graze is small and looks like it’s steadily improving, monitoring is often enough. If it’s getting more sore, more swollen, or not improving as expected, ask your vet for advice.
