'a cold' or sinus issues may be a clue to BUTYL exposure.  Any time you see a product with butyl either; especially 2-butoxyethanol or Ethylene Glycol Monobutyl Ether. http://www.valdezlink.com/re/justavirusorcold.htm  In about 2003 EPA lifted all restrictions on how much could be 'expelled' by manufacturing.  Now no restrictions on how much can be put into the air.  Maybe there is this kind of chemical in the polluted air of CA near you? And since this same chemical is unsafe in many cleaning products, paint, etc ... anyone at any age could be affected.  (Vapors in eyes is a serious exposure) People who live in houses as they remodel them get exposed to lots of this type of chemical and so do their pets.  With way too much exposure autoimmune issues like ALS can occur or any autoimmune issue I would like to know from the National Jewish Health what the leukodystrophy was that only was found in Auschwitz Jewish people.  (A clue that this would be a chemical exposure for the population there of men and women who were forced to worked in munitions detonations manufacturing.)
