So I got a vet out and the consensus is that these are probably granulomas/some kind of granulation tissue from a previous wound/infection or possibly even insect bites–he overreaches so this makes a good deal of sense since he was on the track and somewhat neglected after he got off. We could try high-dose cortisone but it’s very likely they would just come back again and the treatment is expensive and I know from personal experience high-dose cortisone is pretty miserable for the critter on it…I’m thinking about it but not yet sold on the idea.
There is as far as the vet can tell no active infection associated with them. My understanding (it is possibly wrong) is that granulomas can be autoimmune-related as well, in which case not a lot can be done for them anyway
The other option is just to keep them super clean and wrap them in the summertime so flies don’t pick at them (though he was fine all last summer…still don’t want to take my chances) The vet’s not super worried about them.
If anyone has treatment suggestions for this I’m all ears, though I can press on them and even pick them off and it doesn’t really seem to bother him even a little so I’m trying not to be concerned.
