HI. I am a 46 year old woman. Diabetic, hypertensive, not on meds. I am experiencing a sometimes sharp pain on my left side by my ribs. Lately everything I eat gives me heartburn. If I eat red meat I get diarrhea. (cut it down to once a week) Just before my periods the pain, gas, and heartburn are more severe. I have a very busy lifestyle, lots of stress. So although I'm overweight, my job requires me to stand and walk for 7 to 8 hrs. a day. Can you give me a little insight to what this may be?
