Foam rollers in my opinion are one of the most useful pain relief tools you can own, without the big price tag. The foam roller itself comes in many different sizes and styles which make it easy to take with you on the go. The purpose of the foam roller is to break down soft tissue adhesions (knots) and scar tissue by using your own body weight. On a cylindrical foam roller you can also perform a self-massage or myofascial release, increase flexibility, and soothe tight fascia while increasing blood flow and circulation to the soft tissues. So that being said, get yourself a foam roller and look at my website at the correct ways to roll your pain away.
