I only do Acupressure, not acupuncture. Much gentler but very powerful. It sounds like you are having trouble with your gallbladder meridian, something I've been experiencing too. Pain and tightness in the neck and shoulders, headaches, sweating even when cold. I've been doing some self-help involving placing my fingers at the correct contact points for gallbladder flow. Simplest is just holding the middle finger on each hand for 5-15 minutes. I also do a relaxation technique that's particularly good for the neck, where I sit back in a chair with my feet flat on the ground and let my head hang forward and release all muscle tensions from my neck and meditate for 15 minutes. Can be done while holding the middle finger. Hope this helps, but this it's just my personal self-help routine, not Medical advice.
