A simple ice pack is a very effective pain killer and anti-inflammatory. The cold numbs the nerve endings causing the pain signal and reduces the blood supply for a short period of time thereby reducing swelling.
Note of Caution
It is important not to leave the ice on the skin for more than 15 minutes. An ice burn may result.
A specialised gel cold pack works best, although ice cubes in a plastic bag or a bag of frozen peas will do if nothing else is at hand
