hmmm.....

Let me think about this. I will have to do the open mouth stretches and get back to you.

I have had success in the shower, just gently moving neck side to side, with the hot water beating on the side I'm stretching. That's a good one for me. Other than that, they're kind of anti-stretchers, I'm afraid.

My PT used to use a kneading and elongating effort. I thought it helped but not a cure, for sure. Sometimes very painful. Sometimes gave me more pain afterwards too.

Botox helped for about two weeks.

The LED and infrared light pads are wonderful for my scalenes. I can be in a lot of spasms with my scalenes and use the pad on them and that helps me the most. And it will relieve the pain and tightness and I will fall asleep while I'm using it on my scalens. This is a good thing for pain relief and relaxing the scalenes and pecs. Don't know what I would do without them.

Hope this helps...
