Use ice bags, cold packs to provide cold to the injured area. Cold can provide short-term pain relief. It also limits swelling by reducing blood flow to the injured area. Keep in mind, though, that you should never leave ice on an injury for more than 15-20 minutes at a time. Longer exposure can damage your skin. The best rule is to apply cold compresses for 15 minutes And then leave them off for at least 20 minutes.
Heat may be helpful once the injury moves out of the acute phase and swelling and bleeding has stopped. Moist heat will increase blood supply to the damaged area and promote healing.
