Earlier this evening during a conversation with a friend, I started struggling to think of simple words to complete a sentence. For example, the right side of my neck had just started to hurt, and it took me a few seconds and much thought for the word pain to come to mind. It only lasted a few minutes. As my mind started to clear, about 5 minutes later I was helping my friend navigate the map on her phone and giving her directions and the tip of my pointer finger started going numb and them the tip of the next finger was numb too. Eventually, my entire hand was numb. I was just sitting there, I was not leaning against the car door or pinching a nerve (that I know of.) The whole episode only lasted 15 minutes. Should I be worried?
