[|Human|] I have been having pain in upper left portion of abdomen for about 8 or nine months now. Right under my rib cage on the left side. It started out just every now and then, but lately it has been a constant ache. I do have problems with constipation. It has also started hurting in my back on the same side. Do I need to see a Dr. for this problem?
[|AI|]  Hi. Thanks for your query. Your pain in abdomen is for 9 months now - under rib cage on left side - now it is constant, along with constipation and now also started to hurt in the back on the same left side. Read the history and understood your problem. Your problem looks to be due to Costco Chat Doctor. CT scan of the whole abdomen. Test of blood, urine and stool. Colonoscopy and upper GI Endoscopy. This will give a proper diagnosis and a plan for the treatment.
