Too complicated, like people said. The ice is what is doing you the most good. I do spinal injections for a living with big 15-18 gauge needles, and i tell everyone to ice the site 3-4 times each day, for 20-30 mnutes for 2 days, even if they dont hurt. Heat is ok after that. They usually dont hurt until after they get home cuz of the local anesthetic we use.
