Yesterday I had something odd happen to me twice. The first time I was sitting and all of a sudden my hearing on my right side was muffled and my right eyesight was severely blurred. I felt as if my whole right side was just slipping away and all of a sudden withing seconds I was normal again. Then later that night the exact same thing happened but this time I was walking. It caused me to lose my balance and stumble to the couch once again my right side for just a few seconds felt immobile. The rest of the night I just felt confused I would go to say something and completely forget what I was about to say. I would comprehend what anyone else was saying but in a slower manner than normal. I went to bed and woke up feeling completely normal. Now today Ive had a few more odd goings on. My right arm started to hurt suddenly and I got very dizzy but then I went back to normal. What is going on with me? Should I be worried?
