I've been using theracanes for about 10 years. Over the years I purchased a half dozen of them,not because they wear out, but to keep them handy when I need it. I keep one in each of my cars, and both tv rooms in my home. I know that sounds crazy, but this thing absolutely does miracles and I need to keep one close by.
I had neck surgery 11 years ago, and I suffer from constant neck pain that radiates from the very base of my skull down both sides of my neck, the muscles on either side, and into my shoulders. When my pain medication lets me down, I turn to my theracane. Once you learn how to use it properly, and I emphasize the word "properly" it is extremely effective at getting to the trigger points, and down to the very spot the pain originates from. Apparently, by messaging the exact spot, it gets the blood flowing through that spot, as if your doctor just injected a bit of cortisone into it. And even though it increases pain just by pressing on the spot,it "works out' the pain just by messaging it with the theracane. Believe me, it is effective and does work for the relief of muscle pain.
As an experience user of this little gadget, I caution anyone who has similar pain in the neck area to be really careful messaging around the spinal cord area, particularly after a laminectomy where some of the spinal support has been removed. If you slip with this by applying too much pressure, by pressing on those nerves around the spinal canal you could get severe shooting pains down the shoulders and arms. So be careful, even when you become accustomed to using it. I learned all this the hard way, because the pain management doctor that recommended this device to me failed to caution me in how to use it around area of my neck surgery.
With this caution, I highly recommend it!
