More good news. The doctor suspected that my gasping for air spells last week might be the product of small pulmonary embolisms from my leg lodging in my lungs. If that were the case I would have to get on some heavy duty blood thinners for an extended period. He sent me for a spiral CT scan of my chest with contrast yesterday. Apparently, embolisms can be seen in the lungs in this test. I got the results today. My lungs are clear!
