My boyfriend has a rash on his chest, above his stomach, and his left upper arm.  He has had the rash for over a week.  He has applied a cortisone cream and it has not helped.  It is not itchy.  It has some raised indivdual bumps.  He doesnt feel sick.  What could it be?
Hi... It may be herpes zoster most probably. However, you consult the dermatologist for the perfect diagnosis and proper treatment. There may be burning sensation. It is a viral infection and might take 2 to 3 weeks to recover. I would suggest....- antiviral tablets like acyclovir 800 mg thrice a day-steroid in tapering dose-silver sulfadiazine cream-take rest I hope this would help you. Thanks.
