Hi.
Thanks for your query.
Noted the history of
sharp pain in the lower abdomen started 3 days ago and now high into the rib cage, without nausea, coughing, fever or loss of appetite.
There is sharp stomach pain after eating followed shortly by diarrhea.
The commonest causes as per the history I can think of are:
Gastritis or Gastro-enteritis.
Irritable bowel syndrome , IBS as is commonly called as.
I would advise you the following:
Take a PPI like
Omeprazole and Antacid orally.
Send stool for tests to get appropriate diagnosis and get treated if there is an evidence of infection.
Also get the tests of blood and urine and
ultrasonography.
IF the medical management fails to resolve the issue, get an opinion of a Gastroenterologist and further tests like Upper GI endoscopy,
colonoscopy and CT scan to get the further diagnosis and management to get a cure.
