For a few days now my wife would lose feelings in her arm during sleep. She would wake up and be paralyzed in one of her arms, sometimes both, and would need some time to get the feelings back. It happens whenever she sleeps and she tried several sleeping positions to no avail. I checked webmb.com but can't find a keyword that would lead me to a diagnosis. Do any of you know she's suffering from? I plan to take her to a doctor next week but since it's Sunday I just want some opinions or maybe an knowledged answer. Thanks.
