I need some help/advice as I really can't afford/don't want to contact a vet if its unessasary. My 15 year old thoroughbred had a pretty big bruise under his foot which the farrier popped open about 2 weeks ago, he told me to bathe it and keep putting iodine on it all in which I did for about a week. I went on holidays (1 week) came back today and his lower leg is swollen :/ I dunno if its an abseccess or not can anyone help? He isnt lame at all and was trotting around on it fine. The other thing is I found a tick (pretty sure it was paralysis) on the same leg up a bit higher in which a massive amount of pus and blood ran out of when I pulled it out so I dunno if maybe the swelling is from that? Any advice given is much appreciated!
