Today in science class (8th period) almost 2:00 pm someone made a loud noise, and I wasn't scared by it, but I flinched and got dizzy and my eyes automatically closed for a sharp second. Then, I noticed afterwards that I got a headache on the right side of my head... kind of like an eyeache. Then, my right arm started to get numb in certain areas. I've been trying to massage my arm and it isn't helping. Right now, it's kind of burning.

Last night, I was putting a shirt on and I slid my arm in it real fast and it kind of got caught in there and I got a sharp buring pain on the right side of my chest for about a minute. It hurt so bad I almost cried. I held my hand over it and massaged that, too. And it kind of went away. Then, today as my grandmom drove me to my allergist to get my shot, I felt a little bit of pain on my chest. I got my allergy shot today, and where the needle was injected it got "itchier" and "redder" then it normally does and the nurse said there was a hive near the injection sight.

Some of these symptoms are in common with having a stroke. But, I don't think I am having or had a stroke.

Does anyone know what is going on? Or, should I go to the hospital?

P.S. On a website it said to raise both of my arms and if one falls, I may have had a stroke, and that didn't happen. However, when I put my arms down my left elbow went a little numb.
