You could snorkel from the shore. I've sat out dive trips and dive training courses before due to illness or injury. No it wasn't what I envisioned, but in the long run not important.
Personally I would want a well healed peroneal tendon before drift or current diving. And ditch the flip flops.
edit: I work in the soft tissue rehab field, and the Trigger Point therapy pioneered by Janet Travell MD, would not specifically help a torn tendon. You want scar tissue to form to heal the tendon, and Trigger Point tx involves static pressure on the muscle where the Trigger Point is located, followed by a stretch. It's the tendon that is injured here, and stretching too early before the tissue is healed would create more damage.
