Hello lovely MN-ers, desperate for some advice.
I am COVERED in bites. About fifty of them. I don't know what the cause is - I slept with the window open the night before last when most of them appeared so was assuming mosquito, but they are clustered together so I don't know if that would tally. Some of them even seem to be places I can't understand how any insect would get, like my back (I sleep on my back, and was wearing PJs...). People have suggested bed bugs: but is it likely I would be covered but DH not have a single one if it was an infestation? Do I just taste much nicer? 
More urgently, I've come up in hives around the bites themselves - should I just take anti-histamines and grin and bear it (am going slightly demented through pain/itchiness) or should I go to the doctor for something stronger than over the counter remedies? Barely slept last night for the pain, only bags of frozen peas on the sorest ones seemed to help. Topical cream does virtually nothing.
