Skepticism, Science & Pseudoscience

Wikipedia:
"In 1997, U.S. Social Security Administration Commissioner John Callahan issued a court memorandum officially recognizing MCS "as a medically determinable impairment" on an agency-wide basis.[44] That is, without making any statement about the cause of MCS or the role of chemicals in MCS, the Social Security administration agrees that some MCS patients are too disabled to be meaningfully employed"

From the same Wikipedia article (my comments in italics in parentheses):

"A 1999 consensus statement recommends that MCS be diagnosed according to six standardized criteria:[1][34]

Symptoms are reproducible with repeated (chemical) exposures (Mine certainly are)
The condition has persisted for a significant period of time (Some things have affected me for 50 years)
Low levels of exposure (lower than previously or commonly tolerated) result in manifestations of the syndrome (i.e. increased sensitivity) (Yes)
The symptoms improve or resolve completely when the triggering chemicals are removed (Yes)
Responses often occur to multiple chemically unrelated substances (Yes)
Symptoms involve multiple-organ symptoms (runny nose, itchy eyes, headache, scratchy throat, ear ache, scalp pain, mental confusion or sleepiness, palpitations of the heart, upset stomach, nausea and/or diarrhea, abdominal cramping, aching joints).(Absolutely, in my case)
