I have an appt. tomorrow with a functional medicine MD that addresses Berg's theory of hypercoagulation due to a hidden infection. All I know, and I've told my story before, is two times while in the hospital and received anticoagulant therapy for surgery and bed-bound stay, by the time I got home my mind was way more "free and open" (don't know how to explain it). I could FEEL how I used to feel way back before becoming sick. At first I thought it was the IV fluids, because I have POTS and tend to not hold onto fluids that I drink. But in that 15 year time of 5 hospitalizations, I had IVs for all stays, but only anti-coagulants for the two times I felt really good. That is why I am seeing this doctor to have it addressed. I admit it may be pure coincidence, but still, I'm having it thoroughly looked at.
