Does Anyone Have This Symptom?

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!

Hi Namaste,

I don't have trouble breathing when this happens, just the heart pounding and heaviness that seems to only happen when I go from sitting to standing.
