Hello @tsharkey01, I haven't had any voice related problems when my PMR was active but I'm sure you aren't alone. I'm hoping we have some members that can share their experience with you. I did find some information that sounds similar to what you are describing.

" Lung involvement in polymyalgia rheumatica is rare and has been observed in the form of respiratory symptoms such as cough due to upper airway inflammation or vasculitis, pulmonary nodules and infiltrates or vasculitis of the pulmonary arteries or smaller pulmonary blood vessels."

Do you have any cough or other chest or lung symptoms? Have you discussed the symptoms with your doctor or rheumatologist?
