Falling and jolting after a C4C5 fusion

Has anyone ever taken a real fall after aC4C5 fusion!?? I was goi g to the bathroom in the middle of the night with my walker and my walker caught the door and I lost my balance being jolted away from the walker grabbed on the portable seat toilet handle ordered by my Dr. to keep from falling in the tub and from possibly breaking my neck but had to really grab that handle hard taking a big jolt to the neck. Within 5 minutes I min a lot of pain in my neck and head and am terrified I did damage. Is it possible? I’m afraid to go back to sleep and know I will be worse when I get up. What can I do ?

Go to the ER immediately. I never fell like you, but I remember every motion hurt like hell for awhile… Hope you are OK.
