For the past 3 months I have been waking up with pains in my stomach, either right unger my rib cage or right below my belly button. I have had a colonoscopy and the doctor said, I had IBS. Then 2 weeks ago I had a CT scan with contrast and they said, I have diverticulis. Would that cause the pains in my stomach ? I also feel very tired in the morning and it takes me about a half an hour to get out of bed. Any insight would be greatly appreciated.
