Heat: Heat is best. You can use a topical cream like Ben-Gay or IcyHot, heating pads (be careful not to burn yourself, don't use a heating pad when sleeping). Very gentle stretching. You can also take some anti-inflammatory medications like ibuprofen.

Pointless: Not being able to point you toes could be a sign of some trouble. You need to be evaluated with a consult for an orthopedic surgeon.
