Hi, I had a similar problem, severe shoulder pain,i was diagnosed with a rotator cuff injury. I am a massage therapist, and found it was too deep inside for me to be able to reach / massage. The exersizes my Physiotherapist gave me were unbearable as I could not lift my arm above chest hight. After sleepless nights, and painful days, i was at the end of my tether. I was like a zombie for 6 months. The Physiotherapist said there was not much else that could be done except surgery. I asked if he had a machine that could send deep sonic pulses into where the pain was. We tried this and after the 1st session i slept the night, after 8 sessions I was PAIN FREE and have been for over 12 months now. So please dont have surgery, ask if there is a machine with sonic / sound
waves and give it a go. Hope this helps you xx Painfree Angi.
