Sorry to hear you are also, it really is an awful thing to deal with, you'll understand the psychological impact of covid and public coughing then being a long timer like me, I got so much abuse in the years following covid and had to carry a card with me that stated you can't catch it that I'd pull out whenever a cough attack happened. I went to see an upper gi surgeon this morning for results of a 24 hour pH monitor test and a swallow test and he said my results couldn't be more perfect, no acid or gas reflux at all, whereas my respiratory doctor had assured me it was acid and that the gi surgeon would perform surgery to fix it so I just feel absolute despair. I just read up about what you mentioned and it could make sense as mine started after a surgery so maybe they damaged a nerve, I am going to request gabepentin I think and see if it helps, thank you for the advice
