I had my GB removed in Feb. This pain you are experiencing is not uncommon. Everything inside you is still kind of loose and readjusting. I had some moving pain as well after surgery, so I wouldn't worry about it unless it is excruciating pain. It took me about 2 1/2 weeks after surgery to start feeling "normal" again, so you're almost there, give or take! :)
Hang in there and take care of yourself. If you need any more info, please ask.
