Recently, it’s been roughly two months, I have been waking up in the night with unbearable numbness in my left hand (mostly) but sometimes my wrist & arm

I have been going to OT for about six weeks, trying to keep up with a rigorous at home exercise program, so far no relief. Numbness in left hand is 24/7 (aprox. 3-4 level during the daytime)
At night I sleep anywhere from 2-4 hours before waking up with numbness (7-8 level)
The only relief is to get vertical, I have tried a large wedge pillow, a neck roll pillow, beanbag, gel, foam…even no pillow!
I was diagnosed roughly twelve years ago with cervical ,radicliopathy (C5-C-6)
I’ve been able to keep it from getting worse, until now!
I also went for my first Medicare wellness exam and have lost one inch of height, after a Dexa scan, I do have osteoporosis as well…
Can someone advise, next steps?
Thankyou in advance!
I’m very happy to have found this group!
