Hi.
Thanks for your query.
Noted the history and understood the concerns.
BUrning or discomfort on the left side of the stomach for such a long period can be due to the
gastritis, or due to any nerve compression in the thoracic spine.
I would advise you the following in such a situation:
Repeat
endoscopy as one may get an additional signs.
Since you have already been treated for H pylori, with Nystatin, Aciphex and so on, the cause may be hidden in the spine.
Hence I would advise you for MRI of the thoracic spine and get the correct diagnosis.
Also get a CT scan of the abdomen and
colonoscopy as you have not mentioned the exact area on the left side.
Since you have been prescribed
Nortriptyline, there must be a reason and believe me it does not have much of such side effects ans you might have seen on internet.
You can take these safely. Start taking this and you may have a bit of sleepiness for the first few days.
If there is any problem with the investigations, get treated accordingly and if all the investigations are normal one can think of an IBS, that is
irritable bowel syndrome and get treated accordingly.
