[|Human|] I have stomach pain and itchy rectum for the past few days. I have been taking Metronidazol 500mg for a week but it was giving me dizziness, vertigo. I have also headaches, muscles twitches in eye lid, temporal, neck, back pain. I have to go back and see my doctor, I really dont know what I have. Blood work OK, CT scan did not reveale Crohns disease (and another one is negative for brain tumor or bleeding). Could you help oriente me? Thank you very much
[|AI|]  Hi. Thanks for your query. After reading your history carefully I can suggest the following:Since you have already taken a full course of metronidazole, please stop it. Your symptoms are more suggestive of a bacterial enterocolitis with its complications of the symptoms you have noted. You need a good antibiotic active against intestinal bacterial infection, supportive treatment in the form of pre and probiotic, electrolyte powder, multivitamins. Since you have undergone CT scans, Colonoscopy and biopsy may help you as CT scan is not a good investigation showing the interior of the intestines, particularly colon.
