I'm 24 year old boy , and its been around 2 years that rashes have started to grow on my scalp ... to be specific , they started from back of my neck where my hair grow... at first I didnt take it very serious and I thought probably its because of some temporary infection... but gradually when it started to develop , I met a dermatologist and she prescribed some lotion that I dont remember what it was and some antibiotic pills , the rashes stopped spreading. but when I finished my medicine , after about a month , they started to spread again... after about a year and half , of trying to keep the infected area clean to avoid spreading the rashes , now the density of the rashes are decreased , but new rashes are developing on the top of my head... these rashes are often , too tender and can be opened easily and sometimes a white liquidish substance comes out of it , and it bleeds...( the location is about where I started to lose my hair )... when the cyst becomes empty , after about two days the rash reappears in the same place ... its not itchy nor painful as long as its not touched. but when I touch it, sometimes its painful. it more looks like a blotch... and I lose my hair in the spot where it occurs. I took a blood test previous year but there was nothing odd in that , except that I had a rather high bilirubin which is assumed to be for the Gilbert syndrome that I think is irrelevant to my scalp problem. I dont remember to have any major disease , and I haven't even caught cold except once or twice in past 5 years.
The other helpful information is , I used to have too many rashes on my face when I was in high school that I cured it by using Racotan (I'm not sure about the pronunciation) for 6 months. and it got better. I also started to lose my hair when I Was 20-21. about a year before I Have the rashes on my scalp. I used to use Minoxidil but I Gave it up about 2-3 years ago.
I smoke like once in a blue moon. and do not use drugs. and drink beer once or twice a week.
since I always keep my hair short , having the rashes on my scalp doesnt have a pleasant look.
I would be so glad if you help me with a good diagnosis.
