I am sorry you are going through this while trying to control your PMR. I was diagnosed with PMR initially but I too, had jolting pain in my legs followed by numbness in my feet and an ankle. High levels of eosinophils were causing my symptoms and I was eventually diagnosed with EGPA instead of PMR. I was put on Nucala to lower the eosinophils drastically, and my symptoms receded. The numbness went away. I am very grateful to the rheumatologist who connected the dots to this very rare disease. This may only be my story and not what you have, but worth asking about since the numbness in my feet and jolting pain indicated a vascular cause which is not typical of PMR, but definitely of EGPA . Worth asking about?
God bless you and may you find relief from that great discomfort!
