Isis has always had skin issues: rain rot, fly bite allergies, scratches, etc. For the most part, these things last a little while, are treated, and then resolve. For the past two months or more, Isis has had lumps under her legs, right where the girth goes. Initially, the lumps did not interfere with the position of the girth. The lumps were slightly in front. However, wearing the girth irritated the lumps.
The lumps are behind Isis’ front legs right in front of the girth. The lumps appear to be only in the skin: I can move the lumps easily around. They feel mostly hard and small. The lumps are not uniform in shape. The one on Isis’ right side is long and tube-shaped, while the ones on the left side are like clustered pearls.
The lumps have gotten worse in the last week (see pictures).
I’ve tried a variety of things to deal with these lumps and so far, nothing has worked.
- Early May: Clipped the hair around the lumps to try and help keep the area cool in case the lumps were related to the increasing heat. Made sure we had fly spray in case the lumps were fly bites. I tried using Sore No More Sports Salve on the lumps to help prevent chafing.
- Early June: As the weeks passed, the lumps became larger. My vet suggested trying antihistamines, so we started Isis on Histall (which has helped for other conditions). After about a week, the lumps seemed to be softer and slightly smaller but did not go away.
- Early July: Isis has been off of Histall for about a week and she continues to have more trouble with the lumps. They have gotten larger and are harder again. She is having trouble with the heat so she is also on electrolytes. Her IR has flared up (fat pads above her eyes and on her rump even though she doesn’t look fat), most likely due to lack of exercise. It has been too hot to ride most evenings.
My next step will be to call the vet and see what she recommends. Maybe a biopsy? Maybe this is caused by clogged sweat glands. Who knows?
