I have this or it’s doppelgänger.
I’m 99.9% sure that I’ve not had covid, our precautions are mainly full on exclusion.
My missus has a serious autoimmune condition and covid would kill her so we’ve never left lockdown, still wear masks whenever we go to the shop, don’t take visitors & haven’t even been into the homes of immediate family so no family Xmas or birthday celebrations, we haven’t even hugged the grandchildren since it all started (which is the worse of it as means that we’ve never held the youngest).
Anyhow, over the last year I’ve had the regular sore nose thing so it might be due to something else maybe?
It manifests itself as what feels like a cold sore then flares up to form a hard and sore area around the nostril/s.
After weeks of being a Schnozzola Durante impersonator it finishes with a scab inside the nose that lasts for ages and bleeds like glory if you disturb it.
I’m at an age where I get the embarrassingly long hairs growing out of the hooter thing and I can guarantee that if I pluck so much as a single one out then I’ll get 6 weeks or more of the nose issue.
If I trim them it doesn’t happen so I’d supposed that the plucking of a hair opened a route in for some kind of bacteria living in my hooter but I’m not a doctor so it’s just dodgy guesswork.
