@searchingforrelief- Hi. What you have going on is not a “scab” it’s dried hard mucous that for some reason does not clear properly in a certain area. The mucous will sit there, become stagnant, grow bacteria and harden. You start to feel it when it’s finally gotten stagnant enough and needs to get out. Do NOT got to an ENT for this. They are surgeons before anything else and do not care, nor take interest unless they can cut parts out of you. They will create a “maybe” story as to why something is happening and it will all be due to your anatomy, which is not the case. If you feel the need to see someone about it, I would work with a Natrual Path, one who takes special interests in the nasal cavity/sinuses. For now, I would increase water intake, Vitamin C, eat an anti inflammatory diet, use nasal irrigation and humidification. ENTs do. It take the time to educate patients on how nasal mucosa actually works. If they did, they would be out of business. Keep your ciliary function (the little hairs that sweep mucous out) properly. Mucosa needs moisture and a good immune system to work effectively. Hope this helps. Because I know ENTs don’t.

Depending upon your age, you probably don't have adenoids, but your problem sounds like it's in the same area as mine, which I've previously uploaded picures of the thumbnail sized "scab"

For years I was getting the scab about every 4-6 weeks until I had my deviated septum corrected by a local ENT 2 years ago.
After that I was getting the scabs every 3 days.
I had 2 MRIs and a CAT scan – I have really good insurance, but no indication of what was causing the scab.
At one point I took an antibiotic for 10-days, and the scab went away for 2 months … then it came back, though on a 4-5 day cycle.

I had a scab extracted and sent off to pathology, which came back with “Heavy Growth Staphylococcus Aureus”
After over a year of the local ENT trying to figure out what was going on, he decided to send me to the Specialist at Penn Medicine in Philadelphia – The Dr. you go to see when your local ENT isn’t able to find a solution.

He looked at my scans and history, and said yup I’ve seen this before … which was encouraging.
He said that I have a structural issue with my sinus that would be repairable, but felt that correcting the problem with the growth could be done without surgery.

As @nrd1 pointed out, your ciliary function (the little hairs that sweep mucous out) needs to be properly working. In my case, hydration and moisture helped to dislodge the scab, but did not help the underlying problem, which was a staph colonization causing a biofilm to develop. Note that this is a staph colonization, not a staph infection.

The solution for me was to give my body time to repair itself by breaking down the biofilm over a 21 day period. This gave the underlying tissue a chance to repair the cilia
• Clindamycin for 21 days
• Nasal Rinse twice a day – Distilled water (not tap!), saline, ½ tsp baby shampoo, Mupironcin, Budesonide
• Based on where my scab forms, in the upper nasopharynx where my adenoids would be, I must bend over so that when I rinse with the solution, it actually gets to the spot where the scab forms. I find it most convenient to do this in the morning when I shower. If I don’t bend over, then it’s not getting to the area.

Other notes:
• For the 1/2 Teaspoon of baby shampoo, I measured it at first, now I just squeeze in an approximate amount. It sounds crazy, but J&J Baby shampoo is what breaks down the biofilm -- see picture of the rinse ingrediants. I also warm the rinse before I use it.
• Be sure to rinse the sinus rinse bottle every 2 weeks with 1/3 Hydrogen peroxide 2/3 Distilled water. And never use tap water.

Looking forward to hearing if this works for anyone else. I've a long history with this, so the notes above are an abbreviation that I wanted to quickly pass on to you and the others in this forum.

Be well 🙂
