@leehil, do you have root canals? Root canals can cause so many problems because of the highly toxic substances that constantly emit from them. If you do have a root canal, please research how toxic they are and have the tooth/teeth removed. If you do not have root canals, have you used a nasal hair removal shaver? They can pull the hair of the nose out which leaves room for infection. Always use disinfected (boiled) scissors meant for the nasal area.
Have you tried Hibiclens Antiseptic Skin Cleanser? Can you get your doctor to write a prescription for Mupirocin Antibiotic Salve? If none of this works, you may need a course of antibiotics to clear this up. Of course, your doctor knows best. I hope you figure it out.
