Seroma - Please help, my vet's on vacation
About 2.5 weeks ago, my horse got whacked by flying debris (don't ask ...) on her right front leg, front and center, several inches above the knee. The cut was stitched. She then developed a seroma between the cut and her knee. I did not know what the swelling was, assumed it was simply from trauma so I did not act immediately.
My vet came out Monday (6 days ago) and told me it is a sermoa. She had me express the fluid using a massaging action up & out the still-draining wound and apply a pressure bandage. I did that twice/day. On day 3, I got the last of the fluid. The remaining swelling was a firm swelling and there was definitely nothing more to express. My vet said that the pocket that used to contain serum will fill in with a fibrous tissue, and that may or may not eventually reduce.
I continued the pressure bandages. Yesterday morning - 5 days after starting to express fluid & wrap - her leg looked almost perfect and the wound is definitely closed now.
Yesterday afternoon, my farrier came. I brilliantly decided to give her a break from her bandage. She had it off for a total of 3 hours. And the site of the seroma completely blew back up. I was shocked, since my vet had said that the previous swelling would be fibrous tissue.
I was going to FINALLY start her back to work today, but now I don't know what I should do. And my vet is on vacation for a week.
Any idea what caused the swelling to reappear? It shouldn't still be serum according to my vet, but what is it?? Is it OK to put her back to work or will I cause further damage? I'm a bit anxious to get her going as she has a stifle that likes to get loose and I want to minimize that.
