You just reminded me of the story about what happened with Ed Lopat after he won those two 1951 World Series games against the NY Giants. Suddenly he couldn't lift his left arm. Doctors couldn't figure out what was wrong, and so he began the 1952 season on the shelf (what we now call the DL), which he didn't like one bit because he wanted to PITCH, was what he wanted to do! Then, about 1/3 of the way into the season he suddenly remembered an orthopedic surgeon whom he had known in his days with the Chicago White Sox.
He called, made an appointment, and flew out to Chicago to see him. The doctor examined him and said, "Eddie, you have tendonitis in your left shoulder!" (What might have precipitated this problem was the weather during the Series; it had been cold, damp and rainy.) After chewing out Mr. Lopat for not having taken care of it sooner, the doctor prescribed what was then a radical treatment---a series of ten X-rays to that left shoulder. Maybe it's no longer used---but at that time, it worked. When Lopat returned to New York he was pitching better than ever, and between then and the end of the 1954 season he ran up a 33-8 record, including continuing to beat the Cleveland Indians to an unrecognizable pulp.
I'm glad the treatment worked for the elbow pain. It might have been simply something jammed or loose in there, and the electrical stimulation broke it up and now the kid is pitching full blast again. Sometimes that's all it takes, something simple. :baseballpitcher:
