Ok so I have an 8 year old grey purebred arabian gelding. Two weeks ago a he got a bruise in his left front hoof that turned into an absess. We treated that and then a week later he kicked a panel and with his back right foot and that swelled and then 5 days after that he got a huge lump on the side of his neck. It was 10 inches long 4 inches wide and about an inch out. The vet came out (for the third time) and said to do DMSO and furison on it twice a day till it went down. The big one is almost gone now but he keeps breaking out in little quarter size hives at least I think it is hives they are all over his body. Could it be bug bites as well? Would he be reacting to them if he is on Bute and DMSO? Any ideas would be greatly appreciated!!! Thanks!!!
