In addition to what KC stated
SInce he is a PT and i am an LMT. From a Massage therapists standpoint, to deal with the scarring and the inflexability of your arm, a technique known as "Cross fiber friction" is essential here in order to realign the ligament and tendons. When scar tissue forms it does so in a "X" pattern and therefore shortens the ligament or tendon. With cross fiber friction work(which can be uncomfortable) you can facilitate change in the ligaments and tendons and allow them to realign themselves so that flexability can be restored. I wouldnt recommend lifting weights at this time(heavy weights) VERY light weights can be used and used SLOWLY.
So in essence, find yourself a decent MT who can address your needs in your arm.

It makes me mad when people say I turned and ran like a scared rabbit. Maybe it was like an angry rabbit, who was going to fight in another fight, away from the first fight.
