Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
2 weeks is a long time to suffer from any pain and particularly in upper abdomen as an early diagnosis is a must for a proper management to avoid any further complications.
Hence I would advise you the following:
Consult your Doctor asap.
Get a referral for an Gastroenterologist for clinical evaluation, examination, and investigations like Upper GI Endoscopy,
Ultrasonography, tests of stool, blood and urine.
Further tests of CT scan of abdomen and others would be needed as per the preliminary diagnosis to have a confirmed diagnosis.
The possibilities are:
Esophagitis and/or gastritis.
Any liver pathology.
Diaphragm related problems like
hiatus hernia.
Pancreatitis and so on.
Colitis involving
transverse colon.
Go for an early diagnosis so that a proper management can be done.
Hope I have answered your query.
Let me know if I can assist you further.
