I too, have peripheral neuropathy mainly in my feet , just very occasional tingling in hands. It showed straight away when I started taking prednisolone for GCA back in August , 2022. I challenged my rheumatologist that it was caused by the prednisolone and he denied it, but for me , the coincidence was too great. Now , perhaps it may have been caused by becoming pre diabetic from the prednisolone . I'm down to 6 mg now , trickling down half mg every 10 days until I reach 5 mg.
I am now officially diabetic and trying to eat low carb , high protein . My feet don't seem to have improved , perhaps a little. Trouble is that I have gone from being good on my feet for an 81 year old, to being unsure and quite cautious. My GCA seems to be in remission so maybe I just have to be grateful for any improvements at my age.
