Hello there I have read through your question and would like to tell you that itchy red bumps on the legs can be because of a number of conditions most common being allergic reaction and insect bites. A thorough physical examination can help to reach the diagnoses. Depending on what your physician discovers during the physical examination he may prescribe you a corticosteroid cream or lacrosse calamine lotion. He may also prescribe you an anti histamine for a few days. I hope that answers your question. If you have any further questions please feel free to write. Thank you for choosing healthcare magic.
