Last year october, i had operated my gallblader stone by laproscopic surgery. After that, I have no problems except gas issues. Suddebly from last 2 days, i am having pain around naval area where one small incision was done. When I am lying in the bed pain is reducing and when sitting for longer period it is again coming. I cant work properly. It is very annoying. Why this pain is happening?! Is it a hernia symptoms? Though I cant feel any mass or similar things around it.
