“Rash” is a very general term that describes new red or pink spots on the skin. A rash can be localized to one particular area or may be diffuse over the entire skin’s surface. Rashes have many causes from skin diseases like psoriasis to infections to allergic reactions. Some rashes are self-limited and resolve on their own while others may require significant treatment. If you develop an associated fever, chills, throat swelling, headaches, or other noticeable symptoms with your rash, it is important that you seek medical care immediately. Treatment of rashes depends on their cause and may include topical, oral or intravenous medications. Sometimes laser and light treatments are helpful.
