I'm really anxious tonight. Early today my dog of 200lbs decided to come and sit on my chest and snuggle with me for 15min. My chest never hurt after, but now almost 6 hours later whenever I straighten out my back it hurts and feels like a bruising pain. It only hurts when I do that, otherwise if I'm slouching it doesn't hurt at all. I have a history of health anxiety so my natural thought is that I am having a heart attack and something is seriously wrong with me. What do you guys think? Is my anxiety making the pain worse?
