I have experienced bouts of low blood pressure both while herxing and also when not. I also get bouts of wooziness and that awful faint-feeling, and bouts of hot flushes (or flashes).
My LLMD said that the low BP, wooziness, and faint-feeling are caused by autonomic nervous system dysfunction, which can occur with Lyme disease. I learned on this forum that a lot of Lymies also suffer from this, so you are not alone.
I haven't experienced the heavy, tingling feeling on the tongue.
