Been itching for weeks. Getting black specks sometimes white or clear dots and small looking bits of tobacco which obviously aren't tobacco. The black specks are the bugs I believe some are almost impossible to see whereas others are a little larger but still not big enough to make out what they are. I'm extremely sensitive whereas my partner says I'm being paranoid. (I'M NOT!) Changed bed sheets we both bath everyday what are they?? They're not headlice I know what they look like these are much harder to find and get rid of whatever they are! They aren't 'animal' fleas they're too small for that. We have no pets, but around the time this started I had a friend round who works with horses and has a pet cat maybe just coincidence? Help me please!
