I have sore muscles in my neck, chest and back. I am also experiencing lightheadness, which comes and goes. I had symptoms similar to this 1 year ago, went to ER: EKG, full blood panel, xray, $1200 later they said nothing was wrong. I feel better when lying down or hunched forward (my chest muscles don't hurt then). I cannot see a doctor until after 12/1/10 since my insurance will cover a wellness check at that time. We have a high deduct and enough bills from other stuff.
