What's this lump on the put a bet on of my leg?

i just go to put my pjs on and i found a lump on the back of my thigh. it's a solid mass that i couldn't pop... a touch smaller than a golf ball. could this be a cyst?What's this lump on the put a bet on of my leg?
It could be, but it could be profusely of other things too. Only a doctor could tell you for sure. Since some of them could be potentially serious, so see one a.s.a.p. It's not easy to tell by your description. Good luck!
Could be - might not be. Is is frozen, soft, inflammed looking? Maybe a spider bite? How could anyone here know? Get to your doctor and find out.
So let me return with this straight: A golf ball sized solid mass suddenly appeared on your thigh and you're asking ByeDr.com what it is?
I'm no doctor but, maybe YOU should seek one to poke around that lump for a while. Ya know, just surrounded by case. Maybe?
