Hello, i am the son of a 84 y/o patient , my mom in fact who had an accident 1 year ago, resulting in a fracture of the femoral neck. The new hip is fine but the “old” one creates pain because of lack of cartilage as well as arthritis. In additon to several high quality supplements (Glucosamin, hyaluronic acid etc), i just purchased an infrared lamp and an A9 PEMF device this week. I could use either the internal or external coils. What kind of settings could you recommend and for how long and how often would you recommend the treatment? Thanks in advance, Michael
