Question: A month ago, I developed severe pain in my lower abdomen and back. I went to urgent care and from a urine specimin it was found that I had an infection. They termed this as a bladder infection although I had none of the symptoms of a bladder infection. The doctor prescribed Nitrofurantoin/Mac. By the time I finished the prescription, The pain had subsided. Now, I am experiencing the same symptoms--the pain is on the left side of my stomach and back). I went to my family doctor yesterday. They checked a urine sample and did blood work for an infection and all was negative. My doctor said I probably had diverticulosis and there was nothing he could do. I am taking 3 advil periodically during the day and only getting minimal relief. What can I do to clear this up? I know that soon the advil will start hurting my stomach Also what do I need to do to prevent this in the future? I have never had stomach issues before. (I had a colonoscopy in 2010 and was told that I had diverticuli pouches.)
