What is going on underneath the skin when we have pain. Let me show you some ain the economy. The run-of-the-mill sports injury here. Look underneath the surface of the skin, you've got fat, you've got some blood vessel, you've got this layer that we call fascia, that banhat keeps everything in place. When you have an injury you have some shearing forces so you get a disruption or blood invests can be torn and causes bleeding. When it Fors in the space it builds up, causes pressure and expands in a space that normally doesn't have something like that. We call ha a hematoma and that causes pain. You know, you hear this all the time. I don't want to take anything. It's going to pass. It's going to pass. What do you say when we are being so stub 3w0r7b in thinking it's just going to go away. I try to tell people don't bite the bullet because as a trained surgeon we know that actually having pain can delay healing and if you go through the body literally head to toe you can see the effects. Pain can increase heart rate, it can increase blood pressure. In some patients it can cause angina for a heart attack. Your respiratory system. You don't take full deep breaths and can cause poor oxygenation or buildup of secretions leading to pneumonia and your hormones. All of your stress hormones are activated and that can lead to poor wound healing so truly if you don't treat the pain you might wind up with a situation that's worse than the initial injury. So treating the pain and this is one thing that's so confusing. Heat or ice? Big controversy.

You don't want that wrap it ourself and elevate it if possible above the level of your heart. Helps with pain, swelling and can expedite your recovery. When is a heating pad good for you?
