What Causes Weakness And Soreness In Leg Followed By Hand?

Looking back now, Saturday, I though my knees were just sore from setting at a ball game for four hours but I had trouble walking steadily. Now, my r hand is weak and my hand writing is not the same. It is now Thursday, I called my doc who I found is not I on Thursdays. I speak and think alright,just those other issues. My friend thinks I. Should go to hospital, what do you think? Possible mild stroke?
