Anyone who's ever had an asthma attack knows about the chest tightness and why it occurs. Yet what about the chest soreness that occurs the next day? Why does asthma causes chest pain?
The interesting thing to note here is there are no pain receptors in your lungs!!! The reason asthma causes pain is because asthma causes you to breathe the wrong way.
Confused? Allow me to explain with a pithy lesson on how we breathe. (To learn why we breathe click here )
Breathing is the process of moving air into and out of the lungs. Breathing is one of the few bodily functions that can be done either consciously (you control it) or unconsciously (without thinking of it). Unconscious breathing : Most of the time you don't think about breathing, yet you continue to do it. This is an important safety net for life, because if we had to think about breathing 24-7 we'd accomplish little and most life would cease to exist. Air goes into your...
Why does sitting for long periods of time increase back pain sometimes? This question has been studied for the past 50 years and researchers still find controversy when trying to answer the question. At the heart of the dilemma is a mechanical dynamic between body weight, body posture, and spinal disc load.
A loading, compressive force on a spinal disc creates a certain amount of pressure within the disc which is like a marshmallow in between two graham crackers being squished together. This pressure can be measured with special devices inserted into the disc. With various body positions like lying down, sitting, standing and bending forward, the pressure amounts vary and were first reported in the landmark study performed by Dr. Nachemson in 1981 . In this study, he found that sitting produced higher pressures in the spinal disc than standing. So, for the past thirty years, clinicians have told patients with degenerative disc related back pain to avoid prolong sitting because h...
I never much cared for anatomy class. Dead bodies, the cold, and the smell were just not the way I liked to spend an afternoon. Every first year medical student spends hours in the anatomy room because learning the parts is important, but even more important is knowing what those parts do and how they work—functional anatomy. Thankfully, studying functional anatomy requires warm, live people who don’t usually smell. Let’s learn some parts without the smell because if you understand the parts, then you will understand the treatment. Getting down to the framework of your body is the skeleton which holds you upright, otherwise you would be a blob of gooey mush. As part of the skeleton, the spine is your backbone that bridges the span between your head and your butt. Because it is a bridge, the spine has passive, stationary structures (bones, ligaments, and discs) which don’t “do” anything except provide support for the whole body. However, these parts o...
