What Causes Bloating And Gas Problem Post Gall Bladder Removal?

I had my Gall bladder removed in Oct 14. I find myself with bloating and excessive gas problems, and When I eat it feels as if the food is stuck and not going down like normal. Is this a temporary problem? I also been feeling as if I cannot go to the bathroom like I should, It seems to be harder having a bowel movement? Will these symptoms pass. I also still have tenderness in my belly button and on my right side. Is the tenderness normal?
