I am 19 F.
My heart was suddenly pounding and beating very fast. I felt hot/warm and my face became reddish.
I don't know what triggered it, but it's possibly either because I ate too much or I altered my breathing pattern.
This pounding continued for two days. I thought it would stop as soon as I went back to my normal breathing pattern.
From the third day until today (two months after that incident), I experienced symptoms like:
Lightheadedness, Giddiness, numbness, chills, fatigue, muscle twitches.
The doctor ordered various tests (bloodwork, thyroid, ecg, echo, chest xray) which were all fine. He says I'm fine.
Should I worry about anything (eg pulmonary hypertension)?
