I received two bites during the night and was unware of them  until they
began itching rather fiercely.  I applied Lugol's  and DMSO.  Did this
several times.  Everything seemed ok.  After a few days, the itching began
again in the exact same spots.  So this time I am continuing the Lugol's and
DMSO for a much longer time after resolution seems to have occurred.  The
redness and itching is already much abated, but has not gone away entirely.
Hope this helps.  Can't see where it could hurt but who knows.    Best
wishes,  pj
