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

(topics not germane)
I suffer from a chronic external nose irritation: idiopathic paresthesia?(my) Doc says it's sensitive nerve endings. They tingle/throb constantly at the tip(nasal dorsal nerve?) The area below my lower lip is similarly affected. No neuralgia, ie pain. I'm told it may be a common nerve. Swiping yields but temporary relief. It always creeps back. I've tried a plethora of topicals to no avail: OTCs(all) , returns to East Coast manufacturers, and compounded medicine. I don't want to take an oral, I take 6 currently, for such a small localized area. Furthermore, most of the meds I use are analgesics(arthritis) with no significant relief(to nose) I've had this neuropathy for several years.
