Hi. Thanks for your query. History noted of the pain in upper abdomen on waking up in the morning; like a cramp. tenderness present - hurts on moving and any movements, and thought to be due to exercising. This may be due to Peritonitis, meaning inflammation of te internal structures of the abdomen and can be due to inflammation of any internal organ like appendicitis, or so... I would advise you the following: Keep yourself nil orally. Get admitted to the hospital. You need to be examined by a General Surgeon for evaluation. Investigations of blood, urine and most importantly Standing X-ray of the abdomen, ultrasonography and so. If there is an internal problem , you may need an urgent surgery. If this is just due to exercise you will be sent home with proper anti=inflammatory medicines.
