Many people ask, "Should I use heat or ice?". The answer really depends on what kind of issue you are having. If it is more of a joint or nerve issue, the recommendation is ice. However, if you feel that your muscles are tight, then the recommendation is heat.
Heat helps improve blood flow and circulation to soft tissues, allowing them to heal by getting more oxygenated blood to the area.
