David Meigs, keep pushing about the choking. George went thru better than a yr of choking, gagging and an awful cough. This was just prior to his PD diagnosis. Our former MD keept saying reflux, then hiatle hernia(sp). He sent him to a local surgeon saying he needed surgery. We had lots of misgivings about the accuracy of this diagnosis. Finally we bit the bullet and went to our digestive desease dr in Tacoma. He ran a gastric scope, then a 24hr nasal tube and moniter. There was no acid reflux, no hernia. He sent us to a pulmonary specialist. Wa La! George was found to be taking a blood pressure med causing the cough and had a lung breathing test showing decreased lung activity. Put him on 2 inhalers. within 2wks the problem of choking, gagging, not being able to breath all but dissappeared.. We did elevate the head of his bed by several inches.All of these things lead to much relief for George. I have been so detailed so you will understand that you know your body better than anyone else. If you truly have acid reflux, you should be experiencing some heartburn, some acidity at the back of your throat. I do have acid reflux. Raising the head of my bed and taking Prilosec eliminated the problem.Though everyone is different You will have to keep asking questions until you get help and relief. As for whether the choking is PD related everything we have researched says yes. Because as someone else said the esophogus, and all muscles to do with swallowing and digestion are weakened by PD. Hope this long reply helps to encourage you to keep on pushing til you are satisfied. Hopefully with some relief. Do ask Dr Ballard about this. Hugs, Juanita CG for George 74/71/64
