I must agree with crashdummie59, you need to see a Dr. This forum is great for moral support and finding others who know what your going through. First things first get yourself to a Dr. so you KNOW what is or isn't wrong. Waiting could cause you mental anguish and worry, or worse anxiety/panic attacks and you don't want that..

You should go to your doctor and talk to him. He will probably give you a referal for an X-ray. X-rays will reveal any abnormalities.
Good luck
