Thanks to all of you for your replies. Ginger, it probably wouldn't hurt to see both a cardiologist and a neurologist. But neither may be able to answer the question unless they have a great deal of experience treating POTS. During the past 7 months, I have been to 4 neurologists in the NYC area, two of which supposedly specialize in treating POTS. But with the exception of one of these doctors (who unfortunately won't even return my call), none of them seemed to have much of a clue about POTS. We probably all know more from reading on the internet than seeing some of these Drs. (BTW, I have had mild pain in the ears, but a lot of pressure and ringing. I think it happens when my other POTS symptoms are happening, but I am not really sure.) It is frustrating, because all of my doctors new I had the POTS, but diagnosed me with the ear condition anyway. My cardiologist told me that the dizziness in May (occuring 4 months after my POTS diagnosis) could not be related to my POTS, because my blood pressure and heart rate were under control. I think this is totally wrong. Even though my blood pressure and pulse are decent for the most part, right now I am experiencing symptoms of POTS other than the ringing in the ears and the "up and down" dizziness. My hands and legs have been turning bright red, I have numbness, occasionally very rapid heart rate, and severe heat and cold intolerance. I barely had these symptoms on the higher dose of florinef. And I have tried reducing my florinef twice and th symptoms occured both times. I would probably feel better if I just increased it again, but I am going to wait until after my appointment at the Mayo Clinic, which is in less than 2 weeks! I am tired of guessing and trying to figure out my own treatment.
