Heat Therapy
Heat Pack - heat is recommended to decrease chronic pain, relax muscles, and for pain relief. It should not be used with an acute or "new" injury.
Cryotherapy
Cold therapy is used to cause vasoconstriction (the blood vessels constrict or decrease their diameter) to reduce the amount of fluid that leaks out of the capillaries into the tissue spaces (swelling) in response to injury of tissue. Ice or cold therapy is used most frequently in acute injuries. It is also an effective pain reliever for even the most chronic pain. Cold therapy may be administered by using a cold pack or an ice massage.
