Hi I m 21 male 6 0 and about 190 pounds, I m in okay shape I go to the gym maybe once or twice a week but I haven t been lately because of school and work, I have been stressed out lately, and really tired and my diet hasn t been great. But the other day I have noticed that my right nipple was sore and has a small lump or bump almost directly underneath it maybe just a little down and to the outer right, but I can see it poking out very slightly. From what I ve read briefly online theres a strong like 90% chance that its not cancer related since its painful, but I ve also read it could be hormones but I m 21 and I think out of puberty? But I just recently started growing a little hair on my chest and I can t grow a full beard.. I need help understanding what this is on my own before I seek a doctor due to no insurance and me being low on funds.
