It’s proably a good idea to stop swabbing the area with the hydrogen peroxide. It can change the normal flora of the musousal tissue and act as an irritant preventing that area from healing.

I know it’s become a frustrating, daily nuisance but try not focusing on that area for a few days and see what happens. It may become less irritated without the peroxide. In the meantime it might helpful keep your nose moist with using a gentle misting of Ayr or any saline nasal spray a couple times daily. Xlear nasal spray is a very gentle, not medicated spray with xylitol that helps promote healing…that’s been my go-to for years.
A light film of Vaseline a couple times per day and at bedtime always seems to make a difference for me when my nose dries out inside. It’s an accepted protectant used dermatologists for cuts and scrapes.

If you’re in the same type of climate I’m in this year, winter is relentless. We had snow on May 1st…so the furnace is still running! Let’s hope for some warm, more humid air soon and your issues clears up for the summer. That’s an encouraging point also, that it is seasonal. Try these changes and let me know if they help out, ok? Good luck. 🙂
