I had a plate and nine screws inserted into my fibula 3 weeks ago to repair a large spiral fracture. I am now walking unaided in a CAM boot.
I agree that icing it so regularly is unnecessary. My girlfriend is a physio and has me with a heat pack on it every night for 20-30 minutes followed by a few different stretching exercises. Just as the bone needs time to heal, so too does the soft tissue, and to regain its strength. It is important to be diligent with your recovery, without overdoing it.
Good luck
