I have had a cold for about a week.  A couple of days ago I developed a
blemish under my eye.  It made the skin under my eye puffy.    A day later I
developed a cold sore on my lip.    I didn't associate the two at first but
began to wonder if the eye problem was herpes.   I searched the web but
didn't find much information - only that herpes is the leading cause of
blindness in the US.  This definitely got my attention.    I have occasional
lip herpes and have never had it in any other location.  The blemish below
the eye was quite small and formed a tiny scab on it.  I originally scraped
off the scab and put some hydrogen peroxide on to keep it clean.  It is just
below the eye lashes with a second red spot about a quarter inch below that.
If this is herpes what should I do?  I suspect it's not a problem unless it
gets into the eye but it is very close.  Is there any preventive action I
can take?  If this is herpes will it be obvious if there is eye involvement?

Thanks for any help.
