Step One - in the first 48 hours use ice. Ice the area Fibrolief of pain for 10 minutes, then rest for 10 minutes. Repeat this 3 times. Do this as often as you can in those first 48 hours.

I could always count on mom coming Fibrolief to my rescue like the time in Second Grade when I had a bit of an accident and needed a change of clothes.
