Transcript for Acute Pain You Shouldn't Ignore
and I go huh-uh but now on to our series "Erase your pain" talking about acute sports injuries. Almost 2 million a year end up in the er with sprain, fractures but for some, what may have been a temporary problem can become something much more serious. Chicago mom of three Christie o'brien wanted to run a half marathon for her 40th birthday but something went wrong. I felt a sharp pain iny -- it felt like my left hip. I tried to finish the run and it started to hurt. It was very painful. While she waited to see a specialist she ignored her throbbing hip and went for a jog hoping it was just a simple muscle injury. Turned out she had a stress injury in her hip. They said had I continued running on it it would have turned into an actual fracture. The only thing you can do is surgery. There are times to work through sports injuries and other times you should get yourself to the er stat. What shouldn't you ignore? I have to co-exist in the cityut perhs you can takeim H somewhere mro ateprppiaor F a ppyha measol I could have a happier one. Ep Rorter:ut B this morning Kim cattrall is raising some eyebrows after arguing she is in fact a mother even though she doesn't actually have any children. I am a parent. I have young actors and actresses that I mentor. I H eav niecesep news that I am very close to. Reporter: In an interview on bbc radio, the 59-y Sa iyi tngasn' wt her first choice to not have children. But when her life went in a diffent erioctn, Shean beg caring for the young people closest to her. There is a way to become a mother in this day and age that doesn't include your name on the child's birth Ashton. Loving this series. Same. It's sparking a lot of interest. 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. If you ask a doctor, physical therapist, certified athletic taper we all go by this R.I.C.E., rest, ice and right or wrong way to apply it, put something in between it, never directly on the skin, ten minutes three types a day for the first to to three times a day, compression and like to have someone trained wrap it. 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? That's good for muscle spasm. Ice for injury, remember, I and I. Aye-aye.
