I thought that a mosquito bitten me but the mark has turn into a rash white pimple. What is this?

I was sitting at the park on a bench 2 days ago. I been putting avendo on it but the mark hasn%26#039;t disappear. I don%26#039;t have any other symptoms.|||sounds like herpes blisters. I know someone who had a sudden outbreak on back of thigh after sitting on a wooden park bench.





Use calamine|||It may be a boil.|||could be a spider bite, I would go to the doctor if It continues to get any worse...
