For what this information may be worth: I too have been diagnosed with Seborrheic dermatitis on glans of the penis (I do not have it anywhere else on the body). The condition has lasted for about 20 years and was first diagnosed as psoriasis. Only last year was seborrheic dermatitis diagnosed (after biopsy).
The rash has always come back within a day or two after I stop using whatever med I was/am using. For the first 12 years or so, it was corticosteroid creams. Then Dovonex ointment, which worked very well for a while before it seemed to stop working. Now for a year and a half, Protopic ointment 0.1% has worked very well to keep the skin as clear as it has been since this condition started.
I never experienced much pain until last year (before I started the Protopic), and now I'm often in pain. Usually for days after masturbation, but even sometimes if I haven't done anything for weeks. My derm doctor suggested that antidepressant medications have been found to sometimes relieve pain. I have so far declined to go that route. The most likely cause for the pain, I believe, is based on damage to the skin from prolonged use of corticosteroid topicals. In fact, the initial condition has very minor, but magnified after a rebound effect from the initial treatment with steroid cream.
Be careful with the steroid topicals. I'm not saying to not use them. But use them judiciously, perhaps together with the other meds available, along the lines that justanotherguy908 talks about.
Did you find any cure or solution for this? i have noticed the same thing.
Please do let me know if you found any solutions.
i have dealt with the same thing. my scalp and ears are barely a bother compared to having it on my penis. the first time it came up it went away by itself within 2 months and didn't come back for 2 years. then it stayed around for 6-months and then went away. now it's back again on the opposite side of the glans. do not use any corticosteroids down there unless you have no other option. protopic (0.03%) works pretty well, but should be used on an on/off basis due to the fact that nobody really knows its effects long-term. keep moisturizers on it and keep it clean. also, DO NOT overstress it, it will only make it worse. take yoga or exercise for a release, anything where you can channel all of your focus off your condition and towards a positive. it's hard, but by far the best thing you can do for yourself. it's not curable, only treatable (as i'm sure you know), so learn to live with it the best way you can (i'm sure you've been trying). those are the best words i can give.....
another method i've tried is when i have a flair-up, i shock it with Aclovate, a mild steroid for 1-2 days, 2x a day, then protopic for about another2-7 days. moisturize after getting out of the shower. good luck.
I was recently diagnosed with seborrhoeic eczema.
It is mainly on my face but a couple of years ago I had something very similar on the glans of my penis. The skin specialist considers them both to be the same thing.
The blotchiness on the glans cleared up after about a year of using various moisturizers and all that remains is redness on the edge of the glans.
Although I am glad to see it looking better the sensitivity/soreness from any friction, even just walking, really gets me down.
So it sounds like we are in a similar position, I am currently scouring the web looking for forums etc where someone might have some idea of how to deal with it.
I hope someone answers your post.
Good Luck
