[|Human|] Hi About a week ago I had extreme pain in my center upper stomach. It eased off. But now has come back and it is a 9 out of ten. It is going into my back and will hurt constant and pain will hurt more I waves of 30 secs. Or so. It has been hurting for about 2 and a half hours.
[|AI|]  Hi, The most probable causes I can think about are:Gastric ulcer on the posterior wall. Pancreatitis with or without gall bladder colic or due to pancreatic stone causing spasmodic pains. Rare cause about the conditions of the retro-peritoneal structures should also be kept in mind. The best possible ways are as follows:Rush to ER.CT scan of the abdomen can help a lot. Relevant tests of blood and urine. Upper GI Endoscopy is feasible. All these will lead to a proper diagnosis and a plan of management. Hope I have answered your query. Let me know if I can assist you further.
