Thank you for the query.
usually does not last for so long. So as you definitely are not improving, it is necessary for you to seek medical help
as soon as possible.
Such symptoms can be caused by bowels obstruction due to inflammatory bowels disease or colon cancer, stomach ulcers and narrowing due to chronic inflammation, stomach cancer. If your abdominal pain
is more in the upper right quadrant, and radiates to the back, gallstones or acute pancreatitis
I suggest you to do not wait anymore and visit your doctor as soon as possible. Blood work, liver tests, abdominal X-ray
and ultrasound should be performed at first. Upper GI endoscopy and colonoscopy (depending of which disease is more possible) should be considered.
Hope this will help.
