Medical Questions? Ask a Doctor Online!
This is Dr. Diego, experienced in Internal Medicine, Pulmonary and Critical Care.
I understand your concerns. Do you have any other medical conditions? Do you have any other symptoms?
The pain you described could be from a new episode of diverticulitis. Sometime the pain can be around the entire abdomen. The best thing for now is to go to the ED to have a full assessment. I wont recommend taking metronidazole because it can mask symptoms and cause complications. Let me know if you have any other questions.
