lapdance, you probably tore part of your achilles tendon, which runs from the heel through the gastrocnemius(calf) muscle. I tore mine(felt like getting shot in the calf), and not only was it the most painful injury I have ever had, it ended my basketball career at 48 years old. I elected not to have surgery, and I probably have 90% range of motion. Good luck and get some good pain pills.
you dont know hurt son...
