jweisser.…… I feel one of the main problems most of us have experienced is that we did not have a doctor who knew any more than we did. I saw 7 specialists locally and none actually knew anything or were able to help in any way. These were allergists, pulmonologists, cardiologists, internal medicine, ENT, …... I kept trying all of it. Finally, out of desperation I made a call to Mayo's -- they took me right away. Diagnosed within 2 hours...… I have medicare and blue cross..... I was never charged a dime for anything. It was a 10-hour drive but ---- the best thing I ever did. I had lost soooo much weight and everyone (including myself) thought I was dying. I couldn't eat and I could barely walk through the house. And, the coughing was so severe I was never able to sleep. Sat up in bed for two years. I could go on and on...… just saying, whatever it takes, get to Mayo's. It's a remarkable place. Until you've been, you cannot imagine the kindness and help you will receive. My doctor is Teng Moua in Rochester but there are many others with stellar reputations. They need a cat scan and a sputum test to get you on the right track. I do hope you just decide to make a trip to one of their facilities. It will change your life.
