Kinesio Taping is a stretchy, moveable tape. It comes in different colors and stabilizes the injured area lightly by adhering to the skin and applying pressure to the tissues the tape is wrapped around. This is very popular with Olympic athletes who use this tape to alleviate pain and improve blood flow!
They sell Kinesio tape at stores like CVS that you can purchase and use at home. It is important to make sure skin is dry, oil free, no lotion, and sweat free. You should try to not get the tape wet for an hour after it is applied. They say it's heat activated so you'll have a better adhesion if it is gently warmed up with a hairdryer- don't hold too close! Natural movement of the body will generate enough heat to give it a good stick as well! Mostly all tapes are water resistant. Just read the back of the box to make sure yours is! I believe they all offer water resistant tapes such as Kinesio, Kt and rock tape.
