How is your husband doing now? I will be starting one of the two anti-fibrotic drugs shortly, so I wonder what awaits me.
I don't know if any help, but I have had a problem of chronic runny nose for many years. Sometimes caused by certain medications and sometimes other things. My ENT recently gave me a saline nose rinse to try. It actually cleared out a lot of my nose and my nose is much drier now. It is sold off-the-shelf at drugstore so one does not need a prescription.
