How it works
I have suffered with chronic back pain and other muscle aches and knots. Tired of going to the physical therapist for treatments I purchased a palm/nrg which provides tens-transcutaneous electrical stimulation. There are many other similar products on the market that I am sure work just as well but I have to say it's a miracle worker. Place the pads around the pain back, thigh, shoulder it's the most intense massage you will ever get. It relieves the knots and pain.
What you'll need
My physical therapist recommended a similar product for my back similar to the Alec's direct therapy tens device but it was cumbersome and just for back. I actually purchased this device I own at he mall thinking it was a gimmick but so desperate I would try anything. I love it!!!
