I’m sorry that you’re having such a rough time with the symptoms covid has caused you, it doesn’t make anything easier when the people you turn to for help are so very limited with helping you. I agree with you that we gain comfort from taking to others who have similar experiences so I’m grateful for that. I don’t really know how to advise you but what I can say is if you’re anxious and you have reason to be, perhaps your doctor can give you a medication to relieve your stress and ultimately the tightness and pain in your chest, thankfully it’s something that was checked out and your heart is functioning properly but it doesn’t mean that you can’t have pain. I mentioned having rapid heart beats and a beta blocker would be very helpful but having asthma I’m not allowed to take this medication. I take Ativan which is a benzodiazepine and it helps with a lot by easing the tension in my chest and slowing the heart rate down a little, it’s not a perfect solution but it helps and that’s what matters.
