Yesterday I experience vomiting, nausea, dizziness, and trembling. When I was vomiting I experience tingling in my arms and hands and my hands became stiff. I had a small amount of pain in the back of my head. I ended up in the emergency. The doctors did not find anything wrong physically. The doctor order and CT to see if I was having a stroke but nothing was found. Today I am find like nothing happen.
