No surgery. I've had a number of xrays and an MRI due to a singular attack of sciatica in 2010 (left leg) and more recently the onset of bilateral sacroiliitis and even more recently walking-induced numbness in the left leg. The sudden loss of strength in my right calf first happened July of 2023, and there was zero pain associated. It came back however, relatively quickly. It was a historical item at my Nov physical. Recurred in March after a relatively long walk with my family. I responded to the other person's note because he (?) too lost muscle strength without suffering the pain of a nerve pinch. That's what is confusing...where's the pain? That's a long answer. The short answer is I am not yet seeing a spine specialist.
