Hello,

Sympathy.
Did it just start...?
Calamine lotion is the only thing I can think of to soothe itching. Make sure that you're dabbing it onto the skin.
If you do feel feverish take some painkillers, like paracetamol (make sure you don't mix and consume more multiple medicines containing painkillers however).
Taking warm baths (with no soap) every three hours or so can help. Adding some tablespoons of baking power / soda (bicarbonate of soda) may help also.
Unless it's severe, or you are diagnosed of having a weak immune system...then it's a 'let's wait it out' thing unfortunately.
Get well soon though
