People heal and recover at different rates. A specific time course may work for one patient but be "pushing it" for antoher. Although three weeks of recovery time seems ample, only your surgeon can evaluate how you have healed. In addition, how you feel in regards to energy, dizziness, pain control, etc can play a part to your successful return to work. Good luck in your recovery.
Thanks for your help. I thought so.
