Pricking Pain Near The Knee Got Bit By A Bug, Help?

Got bit by a bug, help? - pricking pain near the knee

Today I felt a pain near my collar bone, as if someone stuck me with a needle and thought it was a mistake to beat me, then started burning and itching. Approximately 5 minutes later I was in my car and I felt the same sensation on the chin, so he flew his hand and wiped a strange-looking brown-black insect in my car. I did not regretted the bite, but it was almost chin to burn and really red and now it is a white circle, like a scar. Now my shoulder was very painful bite and the chin is a bit much. Which can be kind of mistake?
