Hi welcome toHCMForum. The diagnosis is incomplete and uncertain. The cause could be adhesions hernia
or cluster of worms or some thing else.
I advise you to consult a gastroenterologist
for diagnosis. you may need to take MRI GASTROSCOPY along with other tests for confermation.
As it is a long standing problem practice diversion technics as yoga
. i also advise some diet recomendations as avoid taking spices
chillies junk foods oily foods. wishing for an early recovery.
