I am a landscaper and use my body for a good portion of my work. I am not in the field very much but still do some very strenuous work. I met Dr. Rotella over a year ago, at that time had a muscle in the upper back that was the size of a softball that would not relax, I could barely lift my left leg and had sever pain when working. After approx. 3 months i overcame all the issues I had. I would highly recommend Dr. Rotella.
