I have had pain starting in my lower left abdomen that goes up to under my rib cage and radiates to my back for approx. 7 months. The pain seemed to have started after doing situps, which I have been doing for approx. 20 years. I have had an mri, colonoscopy, ct scan, ultrasound and all were negative. I am 3 weeks post op for a hysterectomy due to a somewhat large uterine fibroid thinking that might be what's causing the pain. My chiro seems to think it might be due to a cracked left rib 30 years ago, and the upper and lower left pains are unrelated. I had a complete heart workup done 1-1/2 ago and was normal. I'm not sure what my next step should be. Thank you
