A week ago my mouth felt like I had burnt it on hot chocolate but hadn t had any hot chocolate. It hurt to eat for a week. My mouth feels better but I have a red circle, not a rash above my left breast, a slight rash-looking redness on my stomach, a little on the inner arms and inner legs. No fever. I also feel like I have a sore spot under my left rib cage. I m fighting a cold which started on Friday but already I m feeling better from the cold, but I still have the redness above my breast and stomach, legs, and arms. Any suggestions for what s going on?
