I have a long history of skin issues, a year and a half ago I was diagnosed with Eczema, it showed up on places of my elbows and arms and upper legs. I have had a red bump on the head of my penis for about a month and a half now it will not go away even after using Triamcinolone Acetonide Cream USP, 0.1 % well now a year and a half later after 4 sexual partners, and seeing the doctor twice and showing him this bump on my penis he n 99 % sure that it was eczema being in all that he's an MD I'd sure like to hope he's right but this bump will not go away. Yes I do masturbate every other day so maybe that has to deal with it? On my testicles there is a small bump that looks identical and itches and there is a single hair in the middle so I wonder if it has anything to do with the growth of that hair.. the bumps are red they look more intense in hot water. but there is only these two little buggers I dont get it.
