I have a red rash on my armpits and my belly button and another area Ive tried cortisone and neosporin?

do i have a skin disease or ? I'm pretty concerned actually|||Xenaderm|||One of my kids had a rash in similar places also. It might be Rosea. Check with your doctor to be sure, though.|||Its probably a heat rash. My husband gets them all the time. You might want to see the doctor to find out for sure. If you find out it is a heat rash you can use an oatmeal bath that aveeno makes. Other causes of rashes are changes in soaps, colognes, laundry detergent, deodorant..etc.Hope it helps!|||Stop shaving those area's
