I got bitten or stung several times this weekend. i never saw what it was. i have lumps from my scalp to my ankles. they itch. the muscles under the bites are very sore. what is it? no allergies.

Allergies can start: Whenever the heck they want to - some folk develop sensitivity in mid-life to things they never were before. So, don't say "no allergies". But the 'attack' you withstood may have introduced enough foreign serum into your skin and system that major irritation resulted. Ask a good druggist if you have one or a doctor if it lasts or gets worse in the next few days - or before. Why hurt?

Urticaria: Probably urticaria reaction from bites with edema.
