answer:I underwent about 6 months of Acupuncture/pressure treatment a few years ago with the intramuscular electrical treatments and it was BLISS to the 10th power! I, apparently, could take a hefty dose of electricity and I liked the stimulation ramped up to maximum quiver effect. lol It was very helpful for neck/shoulder pain I have that is the result of over compensation of the good shoulder after having an injury and surgery with a pin in the left shoulder years ago. There are many viable alternative treatments, don’t knock ‘em til you try ‘em. The electrical stimulation relaxes and loosens the muscles and allows them to become more flexible. My therapy was a combo of acupuncture points along with the electrical stimulation and followed up at the end of the sessions with acupressure. I left those appointments in a state of Nirvana and the treatments kept me pain free for weeks at a time. Personally I prefer alternative methods unless I am hit by a bus in which case, yes, take me to the ER. ;-)
