No, I realized after your comment saying red ring isn't really correct. My abdomen is covered from belly button to rib cage in a bright red 'rash". It's not raised at all- it's itchy and looks like a sunburn. I'm calling it an allergic reaction because I'm allergic to cats and had the severe reaction right after coming in to contact with one. I originally had hives and was very itchy, my tongue started swelling and after some Benadryl it all went away. The next day I had this. It seems to be spreading to my forearms today. Cortisone shots are not working. If it's a rash and nothing more serious I'm fine being uncomfortable. My wife thinks it's more serious. ( of course )
A red ring can mean a tick bite. Have you been in the woods? Does your dog have ticks? Could it be a bug bite?
