Blogging a Mystery

Last night I went to the emergency room because I was having chest pains on the left side of my chest. I had them before but they went away. Last night they kept getting worse, then I started to freak out, I couldn't breathe, and I got nauseous. So I went to the hospital. The doctors said there was nothing wrong with my heart. They did an EKG and a chest X-Ray and blood work. There wasn't anything weird with my heart or lungs. I went home after 2.5 hours. The pain continued today but was better. I don't know what's wrong. I feel better knowing that it's not a heart attack, but I'm not content because Mystery Pain still persists.
