question: I have had back pain for over 2 months. I have a pain in my left side and when liking down for 4 days I had stabbing pains. I am a diabetic who has it under control with diet and exercise. Some of my stools have been a little yellow. I am more thirsty now. I have lost 3pounds. I am not overweight. I go to the gym 4 days a week along with walking 2days for one hour.
