It's (not) nice to have confirmation . . .

From about midday today my back has been aching something fierce, and my left leg (with its damaged sciatic nerve) has been very reluctant to let me move at all. I know why, of course . . .

All that crud closing in from the west had its usual effect.  It's nice to know that scientists now acknowledge there's something to it.

Do weather conditions really aggravate physical pain?

It is one of the longest running controversies in medicine.

Hippocrates in 400 B.C. noticed that some illnesses were seasonal. The traditional Chinese medicine term for rheumatism (fengshi bing) translates to "wind-damp disease."

But modern scholars have gotten inconsistent results in studies that tried to match weather patterns to reported pain symptoms—leading some to dismiss the connection as highly subjective or all in sufferers' minds.

. . .

Scientists don't understand all the mechanisms involved in weather-related pain, but one leading theory holds that the falling barometric pressure that frequently precedes a storm alters the pressure inside joints. Those connections between bones, held together with tendons and ligaments, are surrounded and cushioned by sacs of fluid and trapped gasses.

. . .

Many patients swear that certain weather conditions exacerbate their pain. Consequently, orthopedists, rheumatologists, neurologists, family physicians, chiropractors, physical therapists—even personal trainers—report an increase in grousing among their clients when the temperature drops or a storm approaches.

"I can tell you emphatically there are certain days where practically every patient complains of increased pain," says Aviva Wolff, an occupational therapist at the Hospital for Special Surgery in New York City, and Mrs. Polatsek's daughter. "The more dramatic the weather change, the more obvious it is."

Both the Weather Channel and AccuWeather have indexes on their websites that calculate the likelihood of aches and pains across the country, based on barometric pressure, temperature, humidity and wind. Changes in those conditions tend to affect joints even more than current conditions do, says AccuWeather meteorologist Michael Steinberg, which is why the Arthritis Index shows more risk the day before a storm or a sharp drop in temperature is forecast.

Cold weather seems to raise the risk of stroke, heart attacks and sudden cardiac death, some research shows. Heart-attack risk rose 7% for every 10 degrees Celsius (18 degrees Fahrenheit) drop in temperature, according to a study of nearly 16,000 patients in Belgium, presented at the European Society of Cardiology last month. British researchers studying years of data on implanted defibrillators found that the risk of ventricular arrhythmia—an abnormal heart rhythm that can lead to sudden death—rose 1.2% for every 1.8 degrees Fahrenheit drop, according to a study in the International Journal of Biometerology last month.

Ever since my back surgeries in 2004/05, I've had an almost infallible barometer in my lower back and left leg - particularly the titanium and steel implants holding my back together. I swear the damn things are made of mercury sometimes, they respond so quickly to changing weather conditions . . .
