I have used the MagPulser for a sore shoulder and a sprained finger. The shoulder and finger pain I had for over a month. After one week of using the MagPulser, it felt like it was healed.
Also I lent the device to my sister to see if it would help her bursitis she had. She was looking to go see a doctor since the pain was so intense.
She told me she was surprise that one of my "crazy things" I have purchased actually worked.
By the way, I seemed to get good results even if I used the "South" pole of the pulser.
