Is lump painful to touch?
Any other health or medical problems?
I have gynecomastia around my left nipple but its not severe and difficult to make out but it is hard and painful to touch unlike the lump under the armpit. However, doctor's have said it is nothing to worry about.
Are you on any medications?
None, except iron, zinc and protein supplements (whey and casein)
Has lump increased in size with time?
I just recently noticed it but I assume it has been there for sometime.
