I have pins and needles in my lower legs and feet, and the skin looks very blue. I also get what seems like electric shock feelings in my legs and feet, and they sometimes feel numb.
I also have GCA which was diagnosed 15 years ago at the age of 54 and been on Pred. ever since, with frequent flares of GCA. I assumed it was the long term use of steroids that has caused my leg/feet symptoms, or could it be peripheral vasculitis ?
