My Husband Went To The Urgent Care On Thursday Evening

My husband went to the urgent care on Thursday evening with neck pain radiating down his arm causing some tingling in his hand, since then he has been unable to sleep but falls asleep numerous times throughout the day almost instantly and wakes up talking and doing things with his hands uncontrollably. When I question him about it he thinks he is working or i have asked him to do something.....
do you think this is a reason for immediate concern, it seems to have gotten worse over the past couple of days
