Yeah! I just looked at the wiki page and it says it is "commonly caused by the use of fluorinated topical glucocorticoid steroids." I DO have asthma, but I use ProAir which I don't think is a steroid one, and it's not on the list of fluorinated/brominated meds. Also about a year ago, I didn't use it for about 3 weeks to see if it helped, that is sort of difficult for me but still reasonably doable, and I didn't see any improvement. Maybe it would just take a bit longer, though? I'll try that again, if it doesn't improve with the iodine. Thanks!
