Wrist pain and finger muscle spasms can be somewhat common with PMR. It can usually be controlled by delaying further tapering until it stops, or possibly increasing a bit until it stops. Depends to some extent how much (if any) pain you are willing to tolerate. Wrist pain was my last symptom to disappear on 30mg. Now have tapered to 15 with no pain. Can be a long journey. Good luck.
