I woke to find that all 5 digits of my left hand are unable to straighten. Too weak. I have a claw I can close with some strength, but not open. Full sensation, no pain. I am a 64-year-old paraplegic (tethered cord syndrome) and chronic pain patient (following 4 surgeries in 6 months) working successfully to cut my meds way down. I m still working as a writer -- that is, I was, till now. I m a mite terrified. It s not Guillan-Barre, as my dominant right hand is unaffected. Help?!
