Have a fitness plan B if restricted by injury

We recently finished up church softball, which was OK with me because I have been on the struggle bus with heel pain. After X-rays, an MRI, and consults with two, top-notch physicians I have been diagnosed with a partially torn Achilles tendon, along with several other things that need to be repaired. Currently, I am on a one-month countdown to a surgery that is not too intense, however the recovery and rehab are long.
