Rash on buttocks

[Shannon74]

About ever 6 months I get a rash on either butt check. It is very itchy and is 3 bumps in the shape of a triangle. The area around the bumps swell up a bit and is reddish. I thought at first it was a spider bite but it keeps coming back. It is very sensitive, if my clothes brush it I have to scratch it. I have been getting them for about 3 years now. ANy idea what it might be?

Hi,

You are suffering from a condition called Dermographism.

'Patients with simple dermographism are asymptomatic and require no therapy. Recognition of the problem, avoidance of precipitating physical stimuli, reduction of stress and anxiety are important factors in medical care. Also, scratching because of dry skin can be reduced with good skin care and emollients. H1 antihistamines are the drugs of choice.'

You could read about the condition at the following links -
