Numbness and pain in your feet is caused by the tendon for your muscle under your foot shortening up causing the muscle to pull on the ends at which it is attached. Icing something like this that is already short is going to make it hurt worse than it already is. Once you release the muscle you should be ready to go again. Here is how to release that muscle:
Foot muscle:
With foot in your lap, place your thumbs side by side at the back of the arch, right in front of the heel. Press in and hold moderate pressure. After 30 seconds slowly raise your toes as high as you can, release the pressure, but hold toes up for another 30 seconds.

Have you tried cold compress? (Ice pack.)
I’ll guess the podiatrist that made your diagnosis recommended surgical treatment.
