Sharp Pain on right side under area when I bend over.. Possibly gallbladder?

I am 23 years old and have been a CNA in a nursing home for about 3 months. In the past few months every now and then when I would bend over to do something for a resident I would get a VERY sharp pain in my side, I'd stand up straight, hold it and it would p and I'd go about my day. I didnt worry about it much at first at all. This past week it's become alot worse and I left work because of it and went to the doctor a few days ago because it started happening EVERY time I bent over and now when it happens it's not just the sharp pain! Now when I stand up to deal with the pain and wait for it to p it's like something POPS back into place and it's extremely painful! The doctor said it may be an inflamed gallbladder and gave me Naproxen (An anti inflammatory/pain reliever). Sense I've never had this problem before he said I may want to look into a career change. But, I wanted to know has anyone else experienced this and what is was and what you did for it? I had a kid a year ago and thought maybe it had something to do with my breats now being DD putting pressure there everytime I bend over? Or is it possible that I may need my gallbladder removed?...
