What Causes Discomfort In Lower Right Quadrant Along The Thigh Bone?

I have had discomfort on my lower right quadrant along my thigh bone right up to the middle of my lower abdomen. I also seem to get these little small bulges that pop out here and there, they don't hurt, but they seem to be in the lining of my muscle tissue. Also feels bloated an hard from right above my pelvic bone up to my ribs. I have seen a few doctors. They told me I had diverticulosis and gallstones. I'm 26 and all the pain is strictly on my right side. Starting to think I was missed diagnosed. Any advice?
