I'm a 17 year old girl, 5'5", 120 lbs, and have fibromyalgia. For the past 2 weeks I've been experiencing severe pain in the area of my ribs, feeling nauseous, vomiting, having dizzy spells, cramping in the pelvis, and belching with a bitter fluid. I'm having trouble keeping food down, but drinking plenty of fluids. I have been to the doctors and local hospital where they've run blood and urine tests and taken x-rays. No answers still, but I was told that it's probably not related to my fibromyalgia. Ideas?
