Hi Jasmine,
Long time no see.

I'm really sorry you're having a difficult time at the moment.

If you're jerking and cracking your neck a lot then you could try wearing a soft neck collar that's not too tight. I have heard of it helping some people, but then again in others they find it irritating and makes it worse.

Have you tried soaking in a bath with some epsom salts?

Sounds as if you need a massage to help ease the immediate tension and pain.

All these things might just be a temporary fix if your tics are changing and waxing, but the more you hurt it's possible the more you'll tic because of the irritation.

Feel better fast!
