extreme low blood pressure and tachycardia

I have written about this before, but really need a dr referral. I am in NYC and can't believe it is this difficult to find a LL Dr. that can help me with my extreme low bp. Two that I have been going to have said take salt...that's not helping much....one said go do a tilt table test, but didn't know where to do it ! I am not even sure if I should see a cardiologist, neurologist, maybe even endocrinologist??(since I think low functioning adrenals are a part of this...)

Several people have mentioned POTS, but my bp is low almost ALL the time (average in the mid 80's/50's, but often in the 70's/50's). I am so tired and out of it and fear I may fall down. I am still managing to go to work every day, but really worry I will fall in the subway or something! Also, I worry that this is causing organ damage. The symptoms got worse when I started treatment in early March (no antibiotics, herbals only). Got really bad, then better (I assumed I have really weird herx symptoms...)Recently added some homeopathics to the mix and its getting bad again...

Tks...

I have super bad POTS. I went to a neurologist and did a tilt table test where I was diagnosed. This was the first time that something came back positive - and she looked at me so confused because she just could not figure out why it was happening. She was open to Lyme, but doesn't know anything about it.... soon after that I got confirmation that it is Lyme.

She started me on fludrocortisone and that helped a little. Then, I added birth control pills back in and gained more water weight which raised it from 85/55 to 105/70ish. There are more meds I can add for blood pressure, but since I am taking so much for Lyme I have chosen not to take anything else for POTS at this time.
