So sorry to hear about the cervical headaches. I suffer similarly. Often the weather is all it takes to set off a pain event.

Have you considered a muscle relaxer at bedtime? That might help calm down the muscles enough to let nerves repair. I take a Flexaril 10mg at night - and plan to do nothing for a solid 12 hours - they make me loopy.

Ice, Ice, Ice. That helps me a lot when Im aching.

And if those things fail, an Alieve for swelling OR a Percocet (not both at the same time!!)

Thats how I'm living with TOS. Best of luck and speedy healing to you!
