cure:sensitive nerve endings(end of nose, external)

HELP ! I suffer from a chronic external nose irritation. Doc says it's sensitive nerve endings. They tingle/throb constantly at the tip(feels like contact). The area below my lower lip is similarly affected. I'm told it may be a common nerve(trigeminal?). Swiping yields but temporary relief. It always creeps back. I've tried a PLETHORA of topicals to no avail: OTCs of drug stores, returns to East Coast manufacturers, and compounded medicine, et al. I don't want to take an oral, I take ~6 currently, for such a small localized area. I've had it for several years.
