Spot/lumps?

Hi there!

I have had today a strange raised spot on my stomach appear along with a similar one on my right ankle and a smaller one on my chest.

The one on my stomach does not itch but the other 2 I have itch like crazy on and off. Any ideas what it could be?

not a great pic but looks like a bite ..keep an eye on it if it gets bigger or a rash spreads out from it see a doctor
