My dad's brain stem stroke 5 months ago,caused his swallow to be too weak to eat,however just the last couple of days he said he feels like there's something in his throat and needs to "clear" his throat. Does anyone experienced sensations returning like this? Also, his left arm is starting to move slightly at the shoulder and elbow in the last couple of weeks and now the forearm is itching like crazy. We think these signs are nerves coming back to life. Any opinions? Thanks!
