Your doctor or PT should have given you some orders. I recall being told in the hospital after my MUA that I had to do it for three weeks. And on that last day of the third week, I unplugged it, wrapped it up and had my son move it downstairs for pick-up by the medical supply people.
A few days later, I had my follow-up with my surgeon and he said I could stop using the machine. Apparently, the order was for six weeks, not three! I don't remember someone telling me SIX weeks, but okay. :hehe:
