Over the last six-to-eight weeks Ive had mild symptoms of lightheadedness, low energy and shortness of breath.  Additional reporting by Greg Joyce in Bradenton, Fla. But at this point, its not that big of a change. As a result, I underwent a series of tests and examinations in New York prior to the beginning of spring training, including multiple visits with a team of heart specialists. Thats a full day for a first day back.
The last 6-to-eight weeks had changes in  exam tests.
