Ice packs (cold therapy) is an effective treatment method for neck pain. Interestingly, applying ice to an area can have some of the same positive impacts on pain, albeit through a different mechanism. Cold therapy works by: reducing blood flow to the area. Heat boosts the flow of blood and nutrients to an area of the body. It often works best for morning stiffness or to warm up muscles before activity. Cold slows blood flow, reducing swelling and pain. It’s often best for short-term pain, like that from a sprain or a strain. ALSO available to purchase for $30
