My little chewie has something that looks like a blister on his foot. It looks like you could pop it, but the vet put a syringe in to see if anything would drain, but nothing did. He said to wait a month and bring him back of it got bigger or didn't go away. Its only been a couple days, and it seems to have gotten slightly bigger, and I almost feel like the vet made it worse by poking it. Anyway, I have an appointment for another vet but I'm freaking out. Does anyone have any advice or anything that would calm my fears? I tend to automatically assume the worst
