answer:I’m sort of lost on “the crevice on the right side of my right nostril” and “the bottom of the crevice” (maybe it’s a good idea not to have your face photographed and posted, I’m just sayin’), but I do know what an eyetooth is. It’s not an i-tooth. Unfortunately, since I haven’t had tonsils as of circa 1959, I can’t help any more with sensations having to do with tickling tonsils. (You’re sure that you’re not being kissed when this is happening, right? It sounds damned unlikely, with you poking crevices in your nostril and all, but I thought I’d ask.) I do know that facial nerves can seem to have some weird pathways, though. Maybe Rarebear or Trailsillustrated or another physician or dentist can answer.
