ARTHRITIS PREDICTS WEATHER? In previous posts (in my threadreader library) I have explained this phenomenon. The cause and effect is related to barometric pressure.

The body is like a sausage, with contained hard & soft tissues. Bones are connected by ligaments, which are highly imbued with pain fibers intended to keep us from injuring & stretching joint ligaments; to protect against being pulled asunder. Remember “Rack” of Inquisition fame.

When ligaments are lax from chronic wear, serial acute injuries, or from one serious joint injury, these injuries predispose joints to excessive range of joint motion & painful stretch of ligaments that tether these loose joints. Those with flexible joints potentiated for injury.

Women with Hypermobility & Ehlers-Danlos Syndrome particularly predisposed to these types of ligament injuries; especially ligaments of pelvic girdle, which can be permanently injured by pregnancy/birthing episodes, slip and falls, & lifting injuries (nurses particularly at risk)

When at sea level & normal barometric pressure, persons with injured joints experience a level of barometric pressure that bears upon the body sausage, & thereby compacting it; causing joints to more greatly form close & to have lesser ligament stretch.

Lower barometric pressures of elevated regions allow the body sausage to expand. Women with loose and injured ligaments often complain of greater pain of their joints at elevations above 4,000 feet above sea level. As the body sausage expands so do major joint laxities increase.

Before a storm there is commonly a lower barometric pressure, & the body sausage similarly expands; allowing joints greater laxity & opportunity to stretch injured ligaments; as joints shift through greater ranges of motion as the sausage expands.

In men, with robust pelvises, ligament laxity more often result of significant joint biomechanical injury; falling from heights & heavy lifting injuries. Yet men have the same sausage arrangement of their body tissues & can be equally reactive to changes in barometric pressure.

So can humans feel changes in weather in their bones? Yes they can & reason is the relationship of physical mechanical forces to tissue integrity. Human tissues are reactive to the variety of Newtonian forces of physics.

After years of studying relationships of human tissues to mechanical forces described by physics, I have increasingly pondered the failing of my medical school professors to relate tissue pain to the ambient gravitational field.
