Insect Bite of somesort

Hello,
I ran across this forum while looking up some information about insect bites.
About a 1 1/2 wks. ago, Me and 2 of my family members started breaking out with bumps. Mine started on my left arm.
They are not pus filled, or anything. A few have been filled with a little bit of a clearish looking water stuff, but only 3 or 4 out of them all. It has since spread to my stomach area, up to my chest, to my right arm, and now is working it's way to my back.
They itch like nothing I've ever had before. It has been waking me up every night about 4am itching.
The bumps are small(not even a 3/4 of a cm. wide/long).
I tried to get a pic of some on my arm, but can't get any good amount of lighting in the picture. Maybe I'll try again later.

I just didn't know if this sounded possibly like something someone else has had in the past.

If you could help in anyway, I'd be greatly appreciative of it.

Thanks,
Sharon
