Officially diagnosed with POTS two months ago, turns out it was a parasitic infection treated and now symptom-free!

I was suffering so much every day, and taking so much salt, drinking liters of water, midodrine to raise my BP so that I didn't faint (I was fainting A LOT.) all my blood tests were normal. I did a tilt table test and my HR went up to 180, I was diagnosed with POTS. Midodrine helped my BP but my heart rate was still high... My cardiologist suspected something else was amiss. Ordered a sleep study, so many labs, and it ended up being a parasitic infection. I traveled overseas this summer so I think that's where I picked it up at. Since taking the antiparasitic all of my symptoms have subsided, the low BP, tachycardia, and dizziness. I am posting this in case someone else is in my shoes, and tested for everything under the sun, except this. I feel "normal" again. and I am so grateful to have found an answer for my symptoms.
