Hey I am a 14 year old boy and I have just found a lump under my right nipple and when I touch it it really hurts I'm not to sure what it is.
Hi Guest,
Some guys DO find lumps during puberty, it's very common and they usually go away on their own.
It could also be a lymph node, from an infection.
Keep monitoring it. If it doesn't go down in a week to 10 days, tell your doctor.
