Last year I was diagnosed with diverticulosis in an emergency room. Pain was terrible so at that time I was thinking kidney stone, ect. It was mainly radiating on the left side and I had it for about a week. They gave me 2=3 heavy antibiodics and eventually it went away.. This time my pain is very similar but basically in the stomach area and into the lower intestines. Thought at first I had a bad stomach flue Over the last week I have had low grade fever which comes and goes and diarea. Thought I was getting a little better but now in the mornings I am very nauseous My diet has consited of oatmeal. It seems to be getting gad again. Just now thought of previous diagnosis. At this point I feel I need to have this categorized I also have cronique back pain so I thought maybe I wrenched my back. Because it is the weekend my Primary care Dr. is not in. Also what about Urgant Care. We are military and I have never had to go to the urgent care or should I go directly to Emergency room which is a nightmare in our city. Please advise
