sometimes when i’m sitting down, usually while thinking about something negative or feeling stressed/anxious (which means my breathing is also a bit shallow or slow), i suddenly feel a moderately painful pinch/zap sensation in my chest that is also felt exactly in my wrist at the same time, like the same nerve was zapped.

is this something that could be due to anxiety/stress? i’ve had an xray and echocardiogram that both came back normal. do any of you also experience this?
