<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have diverticulitis and was prescribed ciprofloxacin. Once I finished my prescription I got a really bad yeast infection. Its been 3 weeks and I still itch. I also take metformin...sometimes because it makes my heart beat fast. So I stop taking it. But Im tired of this rash...what should I do?  <response>: Thanks for your query at Chat Doctor! I am Infectious Disease Specialist! I went through your query!
