Hello.  Sometimes when I wake up I have one or even two small spots that I
notice due to itch.  They are like mosquito bites.  I have one now and there
is a small hole in the middle.  They seem to disappear completely usually,
but I did get one on my hand which has run its course and now seems
permanent, as a small scab of rough skin.  Has anyone ever heard of such?  I
see no spiders or any other bugs in the vicinity.  This has only been an
issue to me within the past 6 months, never before, and my sleeping quarters
has not changed.
