I just wanted to tell you I really feel for you, because I went through the exact thing for over six months. My original PCP sent me to a cardiologist, who gave me a bunch of tests, including a til-table test. He said, "You have POTS, but we're not going to call it POTS, because it makes you sound crazy." I was SO sick at the time, I didn't even care...I just wanted to get better. After 7 days on florinef, I went in for my follow up, and told the guy I was having a tough time with the drug...I felt anxious, had headaches, etc. So he gave me metoprolol and told me to see a psychiatrists, I didn't need to see a neurologist. In his note, he wrote, "It is unclear to what extent anxiety and depression are playing on her symptoms." Lovely. It made me feel totally insane. Fast forward to this week, almost six months later. I finally got into a neurologist..he did some tests. And gee, guess what? It's POTS and autonomic sensory neuropathy. I've suffered all of this time, believing this guy. To say I'm furious is an understatement. If I had listened to him and not sought out a second opinion, I have no idea where I'd be.
