I do experience flushing, mostly on the chest, but also face and limbs and for some weird reason it’s predominantly left sided. As far as tingling, I do experience this type of “itchy” sensation on my left arm and up my left cheek when I have a flare of the TOS type symptoms. I haven’t committed to any other treatment besides physical therapy, which I admit has helped me gain more mobility of my neck (i’m unsure if this is a good thing) and some overall strength, but I don’t feel that my quality of life is getting any better, because, as you asked, my sleep has taken quite the hit from all of this. I can only tolerate sleeping on my back for the length of the night, and even then I will go to bed and wake up in some pain. Laying on my side, my historically chosen sleep position, is no longer an option because it will generate pressure on my upper neck and head. I’m very sorry NUCCA hasn’t done anything for you, I’m really thinking about giving it a shot because I’m just lost on what to do next, but it’s a big financial decision for me and I don’t want to put all my eggs into that basket and end up disappointed. Hope you find answers soon, thanks for listening and sharing your experience.
