Pain in Neck and left side of body

I am a 28 year old female and over the last two months I have noticed something is happening with the left side of my body.  It started with a tingling and numbing pain in my left arm and chest,.  Now I find that I get a pain in the left side of my neck that helps if I put pressure on it.  The left side of my body also falls alseep every night.  I find the the strange tingling and numbing in my left arm and the pain in my neck is happening a couple of times a week now.  Has anyone had any of these symptoms?  Please help...Thanks
