Sharp pain in right intestine after brain surgery?

Look for possible: constipation issues post op along with small incidence of gallbladder issues after surgery and even stress ulcers or inflammation of stomach. Sometimes a condition known as c. Diff. can occur which is a hospital aquired infection of the GI tract. Let your surgeon know so you can be properly assessed.

If this persists: over 12 hours, or worsens, I would recommend emergency dept. evaluation.
