The swelling was hard, but it didn't seem to bother her if you pressed it. They started her on 2 grams of bute for three days.
On Tuesday, the swelling was down quite a bit, but was still there and the swelling was larger on her right side.
On Wednesday (the last day of bute), the swelling was back up but not as bad as it was on Monday and the right side was slightly bigger. So I asked them if the swelling was still there on Thursday to call the vet.
Thursday came and the swelling was the same so they called out the vet and the vet was stumped. The vet could find no evidence of infection, but he did find what could be a tick bite. He prescribed Naquazone till for two days, 2 grams of bute for three days, and Deoxycycline till empty. And he said if the swelling was still there by Monday to call again and they would do blood tests.
Now its back. I didn't get to see it today so I don't know how bad it was because I was told by one of the juniors who was going to rider her for me today. Anyone have any ideas on what could be causing this? Its super frustrating and I'm already stressing out over school stuff.
