So good hearing from you. I really hope they can pinpoint what the problem is .I know that would be a great relief to you. I have had that test done and it was negative as well. I still have the nausea just about every day. Dizziness and lightheadedness too. Food wise I am still a bit limited still. I can eat some homemade chicken and rice soup with added vegetables. My weight is still dropping 20 lbs lighter. This is still very scary to me because I feel like I could die from this and they wouldn’t have a clue as to what happened. I am glad your weight is now stable. Keep me posted when you feel up to it. I am really glad to hear from you.
