Hi Kevin -- Thanks a million for the update. I don't know if I should be happy for you or not. I guess I'm glad you don't have a paralyzed diaphragm but feel really badly that you don't have a diagnosis or treatment plan for your SOB symptoms. I quit reading heart-wrenching posts from hundreds of Mayo Connect members regarding going years with no diagnosis or relief for their SOB issues. Conventional medicine was definitely failing them, and I hope it won't fail you. If it does, please find the best functional medicine practitioner you can and have him/her take a look for underlying causes of your symptoms and treat them. I'm convinced that's the way to go, particularly when conventional medicine fails you. I talked to my pulmonologist today about next steps for me. He's astounded that my pulmonary function test shows my lungs with a paralyzed diaphragm are operating within normal parameters and said I must have had this for a long time for my lungs to be compensating so well. He agrees I'm doing the right things, ie lose more weight and build up my strength before considering surgery, and prescribed pulmonary and physical therapy for me, which I wanted. One odd thing I've traced back to my PD is that I'm grinding my teeth. Anxiety evidently results when CO2 isn't expelled properly and builds up in the body and that anxiety is causing me to grind my teeth. Hopefully, the respiratory therapist can teach me how to be sure I've expelled all the CO2 I can when I exhale. I'm investigating getting a mouth guard in the meantime. I'll really look forward to your next post when you have this figured out and are playing 3 hours of nonstop tennis again. Take care! Nancy
