Thera p mags work for me!
I've been using the Homedics Thera P magnets for over 15 years.  I have severe digenerative disc disease in neck, low back, and loss of miniscus cartlidge in my L knee.  I have recently been getting severe cramps in my legs and feet, and something as simple as turning over in bed can start a cramp with my toes turning under.  This is terribly painful and the only relief was getting up and walking the cramp out. One night I felt a cramp starting and as I sleep with my magnet belts on my bed, I placed the knee magnet at the cramp sight at the outside of my knee.  The cramp receded along with the pain almost immediately.  I just place the magnet where the pain is.<br />I use the large back magnets to prevent a painful episode when I'm doing something I know will usually wind up requiring injections to relieve.  I also use the large mags across my cervical spine for any task like the computer, sewing, driving, etc. NOT FOR USE PACE MAKERS, INSULIN PUMPS!
