tingling sensation in hands
Hey. How's it going? Hopefully your problem is solved by now. I'm going to give you a list of muscles from memory that can refer pain down the arm. Have these muscles worked and your problem will probably be solved (find someone certified in NMT who will work every fiber of these muscles). This will be a list of muscles that refer pain down the arm and also the ones I remember off the top of my head that can entrap nerves.
*Pec major, pec minor, subclavius, and the scalenes (these can be responsible for thoracic outlet syndrome, closing the space between the clavicle and ribs and compression on nerves exiting the thoracic outlet).
*Also subscapularis and serratus anterior. These refer pain down the arm. (since serratus anterior attaches at the anterior vertebral border of the scapula, you might as well have it worked while subscap is being worked).
*Also supra- and infraspinatus, teres major and minor. These can refer pain down the arm too.
*Trapezius, levator scapula, and the rhomboids (this is a safety measure that couldn't hurt, and although none of these have pain referrals down the arm, it might help to releive some intra-joint pressure in this area and tightness in these, in my personal opinion, could contribute to tension in the scalenes , and you'll need to release the trapezius to get deeper into the supraspinatus anyway, so it couldn't hurt).
* Get the biceps brachii and brachialis, the triceps, the wrist extensors in the forearm.
Basically the idea is to leave no stone unturned so that you're having every muscle that could either refer pain down the arm and wrist or entrap nerves that supply the arm. It's also to get secondary trigger points that may have resulted from the original pain pattern. Hope this helps!
