May 2007 I had a lipoma weighing at 128 grams removed from the front upper thigh area. Along with a 7 inch incision straight down the thigh. Four months after surgery, the pain in the ham strings and front thigh was gravely painful. Have a massage therapist perform "deep" massage on the left thigh twice a week for an hourly session.

In 2000 I had the L5-S1 lower disc fused because of back pain and actually no disc at all. Followed up with pain management of getting lower steriod injections twice a year.

My wife has planter fascitis in her left foot and has had steriod injections.

I bought the "Sonic Relief" based on what I read from other peoples reviews and did some research on ultrsound. For three weeks I have used this on the left thigh(including the ham strings), and the left elbow. There is a complete difference of pain level, like "none", and my massage therapist said she could feel the difference in the thigh. Presently using this on the wife's foot and she uses it on my lower back. Her foot is less painful. The elbow feels great and can perform light weight exercises. If this device is that good on the thigh and elbow, I'm sure it will help with the lower back.

This product "works"! Recommend it to anybody with pain.
