Still having problems 4 months later

I am still having some problems 4 1/2 months after my surgery. I am having diharrea, which I expected, but if I am also still having pain where my gallbladder used to be. It used to be occasional, but for the last few days, it is alot of time. It is not horribly strong pain, but it's there. I did try to do some exercise (sit ups) 2 weeks ago, but only 10 of them, and they weren't that vigorous. I thought that it would be ok after all this time. Is this all normal, or should I call my doctor and have him check me out? Please help.
