I have twisted my leg pretty bad n kept working n making it worse, it got to where I almost couldn't get on a sock took a lot of effort n pain. this started in January today it seems to be slowly getting better. it has like three bumps coming from inside it feels n area around them are red burns like a rash. today the one furthest from my knee can be touched now n seems to be recieding, Can you tell me what this is?
