chubacabra,
As firedog said, first and foremost, take care of yourself!
Second, I highly recommend follow the doctor's instructions to the letter. In most cases, his/her recovery advice was developed from years of research and testing of different recovery programs. I'm not saying doctors are always right, but I sure know from personal experience what results I've had when I followed recommendations and when I didn't. Following recommendations to the letter has always produced the best results.
Lastly, DO NOT PUSH YOURSELF TOO HARD (especially beyond recommended levels). Limitations are set for a reason. Trying to force your body to recover faster often has disastrous consequences.
Good luck!
