I was diagnosed with colitis and was put on flagyl and cipro 6 days ago. I take 500 mg of flagyl 3 times a dau and cipro twice a day. I have pains I'm my stomach and bladder and feel nauseous and have absolutely no appetite and not really thirsty. I went back to the emergency room 3 days ago and they told me my inflammation and colitis are gone but I am still having these pains and nausea. The doctors did numerous tests on me such as a ct scan and an ultra sound and all kinda of blood tests. I also have really soft stools that have been almost black since being on the meds. Do you have any advice?
