Me too with low grade headaches and/or/whooshing/ringing. Am stuck in my tapering down from 20 MG prednisone plus LDN to a divided dose (10+2.5) of 12 MG Yesterday I went for a consultation with a good surgeon to set up a date for a Temporal Lobe biopsy to find out if I might have GCA.
He said that since I have been on prednisone since February the biopsy may come back with a false negative. He will be referring me to an Ophthalmologist.
I still don't know if it's the prednisone or the pmr or something else giving me the headaches and ringing in my ears.

All in all I'm still managing my original flare up since being diagnosed February 2023. This is quite a journey we're all on and I'm always grateful when I get good advice from a doctor who seems to know about PMR and is not driven by the profit motive. Also am grateful for this group. ✔️
