I currently taking two antibiotics for a small infection in my thumb, I recently got off antibiotics about a month ago for uti. I recently developed a small rash on my lower left abdomen but not anywhere else, also my kidneys have been bothering me more since starting the antibiotics again even when drinking 8+ glasses of water, and eating yogurt to help my body while the antibiotics are doing their job. Should I go see my doctor? I know one is not supposed to stop antibiotics without a doctors permission, I'm a little worried and don't know what to do.
