hi i basically have 3 lumps In between where my scrotum meets my upper thigh 2 on the left and one on the right. They are marble sized and close to the skin and have no h Some days they're really big and they'll pop if i squeeze them or poke them and then they'll go down to the size of a pea and then fill up again and become painful any idea what this is? i know its some kind of cyst any help would be appreciated thanks:) i'm 17 years of age
