I have had problem for past year. Extremely strong smell of sulphur & infection from nose. Originally thought sinitus, but nose not blocked and sinus CT scan clear. Nose did not run when crying, thought maybe lacrimal blockage, used massage and saline drops, which after a week caused bleeding and small amount of green discharge, also caused, foul smelling pus in corner of eyes and conjunctivitis which lasted for several weeks. Tears now run down nose, but infection continues to recur.
