I have cervical issues and damage,I experience left leg and left finger numbness and weakness.Today I actually have a bad flare up of the numbness,weakness. It seems to be as Dubious said cervical. I don't want to scare you anymore than you are,but possible an error occurred? It doesn't make sense waking up with totally different issue.I had C5\6 disc fusion and have a small herniation at C6\7,and along with other cervical issues. Keep posted on how you feel..lots of ice!! Start with ice on your neck possibly and see if the numbness is affected by that. May give an idea.My prayers are with you Litezoner!!
