i’m 5 1/2 years post gbs. my left hand and both knees are partially paralyzed. i’ve had several emg’s to verify that my left hand and knees will never be as they were prior to the onset of gbs. i agree that aqua therapy is the best, but it won’t bring back what you’ve lost. i would see a neurologist or as i see a neuromuscular specialist and let them decide if you need surgery. i’m not a dr., but i’m guessin’ you don’t. all the best to you. keep us posted on the result.
