magnets worked for my dad
My 81 year old father has a neuromuscular condition in his wrist, hand and arm. Nothing has worked to help the pain, numbness and tingling. He is a TOTAL skeptic when it comes to alternative natural remedies but he tried a magnet bracelet out of desperation and got relief! Unfortunately after a few days of improvement he realized that use of magnets are a no-no if you have a pacemaker so he had to stop using the magnet bracelet.
I have no idea how this anectodal story may help someone with a horse. However, my dad is an educated guy and his excellent response to the magnet therapy surprised all of us. I have no idea if it would help a horse.
