I have a red rash that originated on my upper left abdomen and spreads around my torso on both sides around to my back. I also have some white lines inside my mouth along the front part of my bottom lip that extends slightly into the sides of my mouth. There is no pain associated with either issue, but the rash does itch moderately. I tried taking benadryl thinking it might be an allergic reaction to something, and the abdominal rash seems to improve somewhat with the benadryl, but it does not go away entirely.
