[so_bugged_out]

NEED HELP! I live in an apartment in Oklahoma City (that has NO PETS ALLOWED). Had company spend the weekend (slept in my bed) about 7 months ago. Since then I have battled w/ some sort of bug. It began biting me in my bed or a feeling that it was landing on my face. I could feel it biting me/crawling on me. Noticing more bites on my neck, face, cheeks and arms (usually in pairs, about a 1/2 to 1/4 inch apart and about the size of a flea bite). I HAVE NOT SEEN AND CANNOT FIND ANY BUGS. But while in bed I could feel them biting my legs as well. I went through several different attempts at resolution (general roach/flea/bug spray), Dr's visits (saying they can't find anything wrong w/ me & to take Benedril to sleep and they eventually have given me ambien to sleep easy), I washed my bedding (this gave me a couple days of relief).
But within the past 3 months these crawlers/biting have moved to my couch.
AND WORSE! I have brought them to my boyfriends house! He also has never had pets. It started at his house last month (began on the couch and are now in the bed... unless we wash it every day). He's now getting the same bites on his neck and face and swats at stuff that feels like it lands on the face while your awake.
I've asked my landlord to figure it out and they had an exterminator come and take my bed/couch apart/looked around for bed bugs, found nothing - 2 visits, 2 sprays.
I went and bought a bed bug spray today and sprayed it on my couch. An hour later I sat on it and it was almost like I annoyed the situiation and they were more fiercely biting on/itching me. I do feel it more on my face, neck, hairline, ears etc. I don't think it's lice, as it lives longer than 48 hours after I'm away. I didn't think it was scabies, as it's been spread from one house to another.
Hopefully someone can help. THanks!
