Thanks for posting,
Per your description of the location of your pain (below the right upper quadrant) and associated symptoms + CT scan results (enlarged gall bladder
), the origin of your pain is due to cholecystitis
(inflammation of the gall bladder) and it might be associated to pain from the ulcer (duodenitis is less likely given that the pain will be located more lower around the periumbilical area). Since from the scan you apparently do not have gallstones meaning that the origin of your cholecystitis is probably not due to gallstones, your treatment will be purely non-surgical with antibiotics (for infection), low-fat diet (when food tolerated) and pain medications (avoid NSAID) such as paracetamol
or better still stronger tramadol or opiate derivatives such as codein and it may be associated to antispasmodic medication
such as hyoscin butyl. Also required will be antiulcer medication to treat both the ulcer and the duodenitis such as proton pump
inhibitors such as omeprazole and/or antacids.
It will be worthwhile to discuss treatment options with your doctor after he is settled with the exact cause of your pain.
Hope this helps and wish you the best
