James-have you considered bedbugs? Look for them at night as they are nocturnal. Look for them along the edging of your mattress or the baseboard on your walls. They are easy to spot and look alot like seed ticks. Hope this helps and you don't have them!!
I can't view your link....so ....... that doesn't help. Could be anything??
Flea's, mosquito's, lice, etc....Maybe get it seen too
Flea bites itch like crazy. Did you go outside in the grass or do you have a pet who goes outside? August and September are the months that fleas are greatest in numbers.
