For example, you can hurt your arm and leave it perfectly still, yet pain comes and goes in consistant waves. What is happening here physiologically?
In: Biology
It’s been a minute since my physiology class, but I remember this one.
So you have several different types of nerve endings dedicated to certain signals, one of which is specifically for detecting damage to the body and notifying us of this through pain messages. Call these pain receptors. Depending on the type of injury, pain that comes in waves typically means you’re repeatedly taking the same form of damage after the pain from the first instance should have subsided. In the instance of something minor like a bruise, the afflicted area becomes sensitive to additional stimuli, even something as minor as the pressure caused by the contractions of your blood vessels in some cases, and repeatedly activates your pain receptors in response to that stimuli.
