I have slight discomfort/pain on the lower sides of my stomach like right above my hips. Sometimes burning pain & also loose stools everyday for months now.

I had a ultrasound that came back normal from my doctor then she referred me to a GI doctor he didn’t seem concerned at all, all he did was order a h.pylori test which came back normal. I made another appointment with the GI because I still have these issues but the appointment isn’t until 2 weeks. Should I Just go to the hospital & get a CT scan in the meantime? Does this sound like Diverticulitis ?? What was your experience with diverticulitis, how long do your flare ups last?
