I have had approximately 7 NUCCA adjustments over the last 6 months with no problem. However, about 10 days ago, my NUCCA doctor gave me his hardest adjustment yet. I was feeling great leading up to the adjustment but felt off after. The main problem I’ve been dealing with is muscle shaking (spasm). The worst of it is at my Atlas, where the back of my head just wants to tremble and become stiff as a board. The rest of my body also wants to shake. Has anyone ever heard of this happening before??? I found a little bit of relief last night with medical THC but given this shakiness has been going on for some time, I’m getting concerned. Best cases scenario, this is the first time in my life my Atlas is in alignment and my body is now adapting to better spinal signals?

I should further state that I suffered whiplash in a car accident 11 months ago and had been receiving high velocity adjustments, but stopped because they were giving me vertigo.

Have you talked to the chiro about this, just in an informational way?
Tell him your new symptoms and see what dr says.

Is this one that uses all the high tech equipment or more basic leg length & body assessments?
It is possible they had a off day and maybe adjusted a bit too much....
I would contact them and talk it out..
