Hi i have a bug bite on my lower leg that has been itching and not gone away for over a week. It is red, raised, itchy, hard, the skin is peeling, its oozing a little bit of clear liquid, and looks kinda like a burn the size of a dime. I havent had any pain and only a little bit of nausea with stomach pain but nothing that bad. Should i be worried or just keep an eye on it?
