Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
As you have described you have got severe pain
abdomen 5 months after surgery for hernia
. As you said you got hernia repaired but you didn't mention which side was the hernia.
If the hernia is on left side, we can be sure that the pain is not due to hernia operation.
If the pain is on the right side it could be due to some adhesion
or reoccurance of hernia. It may also be due to some other disease of caecum, or ascending colon
I advise you to consult a gastroenterologist
for diagnosis and treatment .
Wishing you a quick and complete recovery.
