Did anyone ever follow up more on this pnd issue? i have had chronic pnd for 10 years. has progressively gotten better, but still there enough to aggravate the daylights out of me at times. i've tried many homeopathics, nasal washes, colloidial silver, steam, nebulizer, Iodine nasal wash, similasan allergy relief, borax gargles, and the list goes on. any updates would be much appreciated.
