One common question asked pertains to the use of heat or ice. Each has different effects, and their use can depend on which type of effect you are looking to achieve. 
Heat is an analgesic, meaning that it will block the perception of pain. A few years ago, products providing low level heating that can be worn for several hours during the day became popular. These products can be used while being active. They have been shown in clinical studies to provide some good benefit.
Ice is an anesthetic and an anti-inflammatory. While heat blocks the perception of pain, ice blocks all sensations.
