Re: Did I tear my calf muscle?
Sounds like a tear of the muscle that pulls the foot up, the soleus. It's smaller than gastrocnemius, the main calf muscle, but it's still big and important.
I'd say you should get it examined by an orthopedic surgeon, and the sooner the better. If it is completely torn, it must be surgically repaired. If it's only partially torn, (grade 2 or 3 muscle pull) it might heal on its own, though it could take a while.
One more thing that you can try: Wrap the whole area firmly in a 6-inch wide ace bandage to press out the swelling. If it's that swollen, the injury isn't even getting enough circulation to start healing well.
