My headaches are not pressure inside my head, but tight scalp muscles. I wear a CPAP, and that doesn’t help matters. I’ve found that when ordinary things are causing my entire head to hurt, it’s time for a dry needling session with my PT. Insurance doesn’t cover it, but the relief is worth the $85. When the knots in my shoulders are relieved, the pathway to head pain is better controlled. My head hurts most of the time, but it’s just part of my idiopathic small fiber polyneuropathy life now. I hurt all over. But identifying problem areas and releasing the tension ( for a while, it comes back) with a skilled physical therapist performing dry needling is part of my toolbox now.
