Hello. In the last week or so I have developed a red itchy rash on my right shin. It is worse when it is warm (after a bath or when sleeping under the covers) and later in the day. I would go to our local walk in clinic but it is not open until tomorrow morning. I did have this in the same area briefly late last summer/early fall and it went away quickly on its own. What might I try as a home remedy to reduce the itching and redness?
