Torso Rash

Hi...my boyfriend has a rash that has been getting worse for years!  He says he's always had "sweat spots" under his armpits.  The blotches are pink....hardly raised and don't cause any discomfort...they're also obviously not contagious!

Over the last period of time I've noticed the same rash on his neck, in his groin, stomach and now across his back.  It almost looks as he has had something hot splattered across his back....he's not overweight at all, so it's nothing to do with chafing.

I've suggested visiting a doctor, but I guess he's a little shy!  Thanks for your help!

Hello,
It can be due to hives or pityriasis rosea. Pityriasis rosea is a common human skin disease which presents as numerous patches of pink or red oval rash. The rash may be accompanied by low-grade headache, fever, nausea and fatigue and itching. Topical and oral steroids are needed. Water, sweat, and soap may cause irritation and should be avoided in the disease. Topical zinc oxide and calamine lotion are useful for pruritus.
Hives have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.Many cases of hives are "idiopathic," meaning no cause is known. Others may be triggered by viral infections or medications.

I suggest you to get an examination done from a dermatologist for your boyfriend and start with the treatment.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
