@anniesezu812 oh, if you have a very tight knot you will love this (I hope). The release “hurts so good”. I’ve had two different PTs do this. The first one spent a little time wiggling the needle, working for the maximum number of “twitches”. It was extremely painful, and sometimes I had trouble getting off the table ( this was my glutes and quads). But I loved the relief.
My current PT slips the needles in and sometimes I feel a mild twitch. She might have 10-12 needles inserted per leg, or shoulders and neck, whatever. Then she hooks them up to electrical stimulation for about 5 minutes. Much less traumatic, same results.
