I just got a new warmblood x 11yr old gelding and have been riding consistently in my Antares jump saddle for about 3 weeks with zero problems. Yesterday, in preparation for an upcoming 3-phase event, I rode in my friends synthetic leather dressage saddle and neoprene girth. The ride went fine and I untacked and put the horse away. I was planning on riding today and giving him a long bath so didnt worry about getting him super clean after the ride yesterday. When I showed up at the barn today, he had two lumps right on the girth line on his belly, one was really large and the other was significantly smaller, but still noticeable. I have never seen this is 10 years of riding and I am VERY concerned about it. I assume it had something to do with either an ill fitting saddle or girth or some weird reaction to neoprene? I am NOT a dressage rider and this was the first time I had ever ridden in a dressage saddle as I was solely a jumper and just got into eventing. I potentially could have had the girth too tight or not in the right place?
The lumps are not rock hard but they are not squishy either. They are not hot and are not really sensitive to the touch-if I press very hard he sucks up a little but he would do that if there was nothing there as well. I took him to the round pen to see him move and he showed no signs of being lame or having any pain at all. Can ANYONE help me figure this out? If the lumps don't go down in a few days or are bigger tomorrow the vet will be called. (On a side note before I got him he was neglected and left in a stall for 8 months which is why he has scratches and cuts all over so he is being well taken care of now but prior to the few weeks I have had him he was a mess) THANK YOU !!! b.jpg
