If i touch the very tip of my nose, it is very sore. no redness. nose is often dry feeling inside. this soreness has gone on for days at touch. why?

Odd complaint: but it doesn't sound too serious. You should probably avoid touching your nose altogether. You can use a warm compress if you want, and breathe in the moist air which could help with dryness. If you get any rash or PAIN (without any touching) on the face, unless it is just a pimple and goes away, you should be checked. If you haven't had Shingles vaccine, consider it.

Vaseline: Use a finger to apply a speck of vaseline or Aquaphor inside both nostrils against the septum twice a day.
