I have a HR increase of 45 bpm when going from supine position to standing, accompanied by dizziness, fatigue, brain fog, sinus pain, low grade fevers, facial flushing, and loss of balance. I am being told by local physicians that without a drop in BP that I cannot be diagnosed with POTS, which is contrary to all of the information I've read on the internet. Without the diagnosis I don't feel like my medical attention is as aggressive as it should be.
Who is right? Can you provide me with text or an online link to a "medical bible" that I can use as information to disprove them?
Thank you so much for your help!
