Please suggest a way to cure my elbow and shoulder pain.

Hi doctor,

I have had pain in my right elbow and shoulder for a couple of weeks. I lift heavy weights and work out every day. I am doing this for many years, so this is nothing new. But, it is agony now to hold the bar in squats. If I am lying on the floor with the elbow at 90 degrees, I cannot put the rest of my arm on the floor. Also, wearing a sports bra, etc., hurts me and I cannot rotate my arm to try and reach my back. When I am sleeping, I tend to wake up with my arms straight out and above my head, since this is the least painful position. On the last day, it is also painful to just stand with my arm straight down, feels like something is ripping across from above my sternum to my deltoid. Is there anything you can do to help with this? Either exercises or stretches, which one will be helpful? I cannot recall anything happening during a workout that has caused this.
