well, seen the doctor..yes my left arm is a little weaker than the right (it's also the one injured AND I'm left handed) and there is peripheral nerve damage, turns out I had complained about how my arm felt two previous times since 1982 (don't remember it)...and stopped by the ortho docs office and received my appointments for the pre-op and the echo cardio. I post them if anyone's interested (my whole weight loss has been to point me to this chance to get my knee fixed).
