Ok so I'm going crazy here.. did a thorough sweep of every cm of my couches washed and bagged all my clothes just in case and constantly clean when I'm out of the house I dontnitch not a trace of bed bugs nor fleas I have two dogs and a cat that I recently treated with some kind of skin disorder thought maybe it could have been him but my friend experiences the same thing on his when he sits on the couch for only a few Mminutes it mostly happens around night time... sometimes no bites other times tiny raised bumps a lot like a goosebump and my legs and stomach itch the worst... I'm going nits. What is it
