So I had the surgery and now I am using the infrared light to help the wound heal. I really think it is helping. Interestingly, they used an infrared heat pack on my head right after the surgery to help speed healing, so I know I am on the right track. The main reason cavitations come back is lack of blood flow to the area, and this really gets the blood flowing. Probably the most important time to use the infrared is AFTER a surgery. They're great for wound healing.
