ALMAG+ HELPED ME RECOVER FROM KNEE SURGERY

I purchased an Almag+ (love it) from you a little over a month ago in anticipation of total knee replacement surgery. I had the surgery and have completed a course of treatment with the Almag+. The manual says I should wait 6 to 8 weeks before doing another treatment, but obviously I am not completely healed yet. Do I need to wait or can I start another 3 week treatment course now?
