On Friday 03/07/20 was working when I felt my heart fluttering it started in the left side of my chest. It was really strange, could not put it to words how it felt. I was heating up, so I stood up left my desk and laid down on my bed for approximately 20 minutes then after that exact time everything went back to normal. Now I'm so scared so I'm really careful of what I'm eating, drinking or how my daily routine is, it really shook me up. I'm doing breathing exercises, having healthy meals, drinks and in the morning taking my time to get up from bed.
I feel like now it's not as bad as that day but do get an ache or fluttering feeling which subsides.
I have been booked in for ECG and Blood test next week.
Could this be anxiety, stress or something really wrong with my heart?
