To be on the safe side, I would have it checked, it may be nothing, but, with some of the symptoms you described, I would definitely have it looked at.
Idk wat it could be but it sounds serious, you really need 2 get that checked out. But i hope all is well and that you get help pretty soon
possibly a fluid filled cyst my daughter suffered with the same problem and after a visit to her gp and a course of anti biotics it cleared up.its quite normal try not to worry
Dude! That doesn't sound like something you want to be asking random unqualified people! Go to the DOCTORS, like now! It could be something simple like an ingrown hair... or could be related to your sweat glands... BUT it could also be something a bit more serious that they can treat now? Not to freak you out, but you can never me too cautious with these things. Goodluck!
