What Causes Swollen Eye, Bumps On Face, Red Bite Marks On Limbs?

last friday night we stayed in a motel. throughout the day saturday, i experirnced a progression of red bite marks primarily on my arms and legs. looked it up on the internet and it would seem most likely that bed bugs are responsible. today - day four , I woke up with one swollen eye. I ve taken some benadryl type stuff, and slept and now the eye is even more swollen. my face also has some bumps on it, but they don t looklike the other bites, so i m thinking it s more likw a rash. I m discouraged because whatever I try seems not to help.
