While this painful condition can force you to retire from a match, it is fortunately not life threatening. U.S. HealthWorks Medical Group, which operates a Tacoma urgent care center, says that home care is usually enough to resolve muscle cramps. To begin with, you can apply an ice pack on the site for about 20 minutes to ease the pain (for extended spasms, though, a hot compress may also be applied to loosen the “locked” muscle). Stretching the muscle can also help it return to its normal position. For instance, if the cramp occurs on your calf, stretch out your leg and pull your foot towards your head. Standing on the cramped leg can also be beneficial.
