Can't rotate forearm

I fractured my forearm and was in a hard cast for about 2 months. When the cast came off, I was told the forearm was 90% healed. It has been 3 weeks since the cast has come off and the part of my forearm where the break was feels fine. however, i am not able to fully rotate my forearm. I can get my palm to face up but not to face down. will this problem fix itself in a couple of weeks? or will i need surgery of some sort?

This should have been answered by your doctor, or you should leave a message with the nurse. When the cast came off, you should have been instructed on soft tissue recovery exercises.
It is most likely tendon tightening, from 2 months of immobility. You should start with hand squeeze exercises and  wrist and arm stretching exercises.
