I have a rash like that too that started in october of this year 2015 and now december and the rash is still there no symptoms not itchy,sclay,dry, no bumps and only on one area of my stomach there are about 10 of them on my stomach and one under my left breast (I'm male and have no kids) I searched all over the web and closest I found was either a protein hystamine problem or nothing at all and will go away on it's own..I too have no insurance however getting insurance in Jan 2016 already got the ball rolling with that I do have free clinics all over where I live but also terrified to get checked since I smoke and cancer runs in my family I used to be sexually active but really haven't done anything in months at all and still don't REALLY praying it's nothing serious like STD, STI or Cancer really hoping it's nothing and infact a protein/hystamine problem. I do suffer from Ceciliac Disease (Allergy to Gluten) and do from time to time still enjoy gluten products. I have had this on my thigh before but was only like one or two or three spots and they stayed there for a few months and went away on their own never came back till just this past Oct only now on my stomach and one small one on under my right breast hasn't spread anywhere and it's asymptomatic (no symptoms and haven't been sick either with flu or anything for a looooong so no symptoms at all followed it).
Observe the condition for several days if more will come out or it will grow itchy. If it does then that's the time to check with a doctor.
I am 30 year old female. Have had 1 child. Had chicken pox twice when was kid.
