I'm not sure if this is from Lyme, but I suspect it is.
When I go from sitting to standing, my heart pounds and I feel a "heaviness" in my chest and throat area. I don't know if this is a Lyme symptom, or something heart or GI related?
It pounds hard for a couple minutes, and then goes back to normal. No fast heartrate, just pounding and heaviness.
Any clue as to what it could be?
Thanks so much!
