hello, i have a small,pea sized lump at the top of my ball sack and near the thigh,it is red and somewhat tender to touch but i can squeeze around it and it feels like there is a tiny hard ball or knot on the inside of my sack, please reply with help and once again it is at the top of the sack and starting of my penis and it is also on the right side. i am 21 yrs old, is this normal and should i have a doctor check on this imediately or should i give it some time to heal on its own?? i just noticed the lump today and i dont think that it was there in the past
