Last week when we got back from our trip to Maine, on the drive home all the sudden I couldn't breathe very well. It wasn't my asthma either, but I felt this weird squeezy pressure on the left side of my chest. Was actually quite painful. After it didn't go away for an hour we went to the hospital. They kept us there for a while, but actually got me in pretty fast. Did an EKG, x-rays, and a blood test and nothing showed up. After a few hours the pain went away. But ever since my lungs have felt tight and a little sore and now I'm having a similar pain on the other side, and more central. Not really sure what to do.
