Hi there! I have a rash that is on my inner thighs. It feels like its under the skin. Wondering if it might be a mild case of the hives. It ususally flares up at night and becomes so itchy that it's hard to sleep. I'm wondering if its because I recently started smoking cigarettes and wonder if i'm experiencing an allergic reaction. I know for sure I'm allergic to sulfur (which I'm not sure is in cigarettes or not). I also recently started getting a cough and am having sinus problems because of it! I'm quitting for sure but was just wondering if anyone knew what it could be.
