My grand daughter has theses symptoms. Nausea, vomiting, stomach pain, diarrhea, heartburn, bloating, hot flashes, paleness of face, weight loss, excessive sweating, cold intolerance, joint pain, muscle pain, fatigue, light headed, passing out, rapid heartbeat, low blood pressure, chest pains, frequent urination, hesitancy in urination. Also asthma like symptoms during exercise. She vomits if she eats anything, or even when she doesn t eat. She has had an endoscopy all was good. Still waiting for pathology report. Upper G.I. was okay. All her blood work was good too. She does not have all these symptoms all the time, but has many of them all the time.
