I got dry crusty stuff at the back of my nasal wall and was recommended to do neilmed sinus rinses every day. will it take maybe several tries or more to wash that stuff out? will it come out eventually if i keep going?

It's possible that it may take several tries or more to wash out the dry crusty stuff from the back of your nasal wall using Neilmed sinus rinses. There may be a slight improvement if you use the Neilmed hypertonic solution. "The crusting score was found to be significantly lower in the hypertonic " https://pubmed.ncbi.nlm.nih.gov/28325622/ You can always check back with your provider for tips.
