What Could Be The Reason For Pain In Lower Back, Groin Considering Having Fibroids And A Kidney Stone?

Hi my stomach is feeling heavy and hard after I eat, walk, and dance(I do dance aerobic for exercise).My stomach has gotten bigger since last summer even with healthy and exercising. I have been to doctor and she said I had two small fibroids. I gained 1pound in a week, but loss 6 ounces the next day. On Friday I felt a little sick in the morning, but was ok a little later to go to work. While driving to work I started feeling a sharp pain in my groin area, so I loosened by belt, the pain was a little better, but then it came back. By the time I dropped my sister off to daughter my lower back and lower and upper abdomen was in pain. The pain even went to my right thigh. I had to leave work and go to the minor ED where they gave me an x-ray. They did not give me any results, but sent me straight to the main ED. They checked my gall bladder, liver and heart with an ultrasound and gave me a ct scan. They gave me morphine for the pain. The iv contrast and morphine made nausea and sick. They said they could only find a small kidney stone that shouldn't cause the pain I was going through. Today I am still a little sharp pain in my back and my groining area and lower abdomen sometimes it seems to be getting stronger but stop. I also keep peeing and keep having to make a bowel movement. I am not constipated, because I have a movement every day. I am not pregnant, so I was wondering if the fibroids are bigger or could it be something worse.
