Went for sleep study the other night, "wired for sound" LOL, and during night they came in and added CPAP machine with humidifier. Slept like a baby and felt very refreshed next morning, which is unusual. On way home started sneezing, allergy like, not like a cold. 2 days later, still sneezing and dripping but not like a cold. Could it have triggered an MS reaction or just an allergic reaction to the humidifier? I know I think they are supposed to use distilled water but I am allergic to city water with chlorine. Allergy pills not working BUT if I am laying down asleep, no sneezing, no dripping, which is clear……..very puzzled
