@colleenyoung Thanks for your comments! No, I visited these specialists in their own clinics. The cardiologist and pulmonologist talked to each other. For neurology, I have seen two general neurologists in town and one neuromuscular specialist at Duke University. The neurologist at Duke don't think the basal ganglia calcification is linked with breathing issues. In the beginning, my pulmonogist thought it was neuromuscular problems as MIP/MEP is related to muscle strength in the PFT report and I have muscle twitches. He referred me to see the neuromuscular specialists. The EMG/NCS reports came out normal. There is no disease for my symptoms. Not sure which neurologist specialist to consult.
