hi, i'm so glad i found this site as i'm very scared what could be wrong with me. about 8 weeks ago i started 400 mg of magnesium oxide to help with my bad headaches, it caused my stomach to go haywire, so i quit. the symtoms never went away. i have constant gas trapped in my upper and lower gi tract, last nite felt like a heart attack, i feel very full after small amounts of food, urinate frequently. however, i am usually not constipated, or never have diahrrea. i get gassy with or without food, and the pains are bad!!! i'm meeting with my gyno tomorrow as i love her and am hoping she'll point me in the right direction. i had a pelvic ultrasound 10 mos ago, no worrisome findings. any ideas please??? thanks
