I am new to NT and had injections at the trigger points at the back of my head. I didn't find immediate relief but its worth a try. I 've been told I had hyperexcitability of the upper cervical dorsal rami nerve roots to unraveling of the myelin sheath to occipital neuralgia. I honestly don't know for sure what is wrong with me . I guess its just hard to diagnosis. I wish you the world of luck and I hope and pray you will find relief. a word of advice, STAY POSITIVE.
