Neurologist found that I had a very tense neck, recommended Dry Needling. I have 24x7 headaches / Migraine - level 8. After 1st session, first time in 4.5 years I didn't have headache. The effects lasted 3 hours. After 22 weekly sessions, I now go once a month. Still have headaches/ Migraine down to level 6, just not from tense neck. Range of motion turning head was 28 degrees, left and right, at start and painful, now 70 degrees no pain.
I find the electrical current through the neck muscle very relaxing - 4 needles. Typically goes for 2 minutes, sometime I request 3 minutes.
