I have PMR and when I had a CT of my shoulder for replacement surgery a small nodule was seen on my lung. I then had CT of both lungs and no additional nodules were seen on the lungs but then was seen a small and a larger nodule on my Thyroid. A biopsy was done on the larger one due to its size and it was benign. Doctors were not very concerned about them, they will rescan them in a year and told me most older people have nodules they just don’t know it. I have decided not to worry until something changes. Plenty of other issues to be concerned about and with PMR we need to avoid unnecessary stress. Best wishes to you.
