So, I wanted to get some opinions. I think I have a cyst on my back, but I am not sure. It's a little smaller than a dime, and it's a bit hard. It doesn't hurt only when I press on it, but it's like when you press on a sore bruise, so what do you think? Oh, and do you know any good sites where you can ask a doctor for free online? Thanks!!

Not even a doctor online can diagnose this cyst. You must go to a real-life one for a proper diagnosis.
