dizziness

Posted By Tommy on December 13, 1998 at 21:00:11:







Hello,
I am a 26 yr old male with a history of high cholestrol.  Two months ago,  I experienced an episode of near syncope followed by a couple of days of lightheadedness.  I have had a full cardiac workup including echocardiogram w/stress test and 30 day event monitor.  Everything has turned up negative.  In fact,  I am probably in good physical shape as I have been an avid weightlifter for 12 years.
However,  I have continued to experience days of lightheadedness and another episode of near syncope although nowhere near as pronounced as the first.  The lightheadedness has me extremely worried as it is persistent throughout the day.  
My question is this:  what should I do next in terms of diagnosing any illness or ruling anything serious out?  My internal medicine doctor doesn't seem to think much of it,  prescribing Paxil for anxiety.  I imaging that I will have to ask to have any further testing done.
Thanks,
Tommy
