I (again, i know) have to say that cardio has worked great for me.
Some things doc told me to watch out for also-
- like NoName mentioned, any pressure on the elbow is bad.
- No holding things out at arms length.
- I have lost alot of strength in my left arm, so gripping "large" things like a half-gallon of milk is a no-no, because it causes MORE pain
- Dr. also told me to make sure i wasn't holding my shoulders TOO far back, because that can put pressure on nerves/arteries.
