Went to a bonfire, got dozens of bug bites, unable to sleep and have fever, what can I do for relief??

Fever?: If your body temperature is over 100 degree F for no other reasons (not just a feeling of fever), the bites might have been infected since bug bites are not usually associated with a fever. (West Nile fever is a problem in many parts of the country from mosquito bites) If you truly have a fever, you need to see a doctor now. If not, then they will likely subside unless you see pus forming. ...Read more

Can very dry skin cause red itchy bumps that look like bug bites? I'm getting sporadic red itchy bumps on face it's very dry and itchy!

Yes: Skin that is very dry can develop irritation. The best treatment would probably be to use a cream that is both an exfoliant and emollient. I generally recommend either a lactic or a glycolic acid cream to help get rid of the dry, rough skin.
