I Received Three Immunizations And Had Blood Drawn Two Days

I received three immunizations and had blood drawn two days ago, and now a lot of strange things are occurring. I have these small red dots popping up. And my friend grabbed me and I bruised/(bleeding under skin not sure) very easily. I had pain in my right testicle. I had a feint pain in my right thigh and foot. I had a random allergy attack. My arms were very sore the day of the shots. I'm very paranoid and am in search of an answer. I'm 10-15.
