Hi , I fell in December 2014 and had bi lateral quad tendon repair. i was in rehab for months. I started walking again but my knees would lock, then I started to shuffle. Went back to PT became worse. Long story short I went to neurologist had EMG of right arm due to weakness, and cervical MRI. Had acdf surgery on x2 in JUly and again in August.. No improvement . rain. Tried me on anti parkinson med with no effect. My right arm is very weak still and left arm is weak too. I have freezing gait . Also had a spinal tap to R/O MS. I have to use a walker all the time. Starting PT this week. How long does it take for the nerves to repair . Has anyone else had these problems.
