Always best to have unusual symptoms checked out. It may be nothing to worry about but I find it is always best to hear that from my doctor. Not decide for myself! It could perhaps be something indicating a problem. Maybe not! Make that phone call! 🤷♀️
Are you short of Breath and having Chest Pains? If the answer is YES! Why are we even talking about this? If it hurts to take a deep breath. then you might be coming down with something.
Yes heart racing all day is no good could be A-fib I’d go get it checked out before you have a heart attack or stroke who knows I’m not a doctor! But your body will send you signals when something is wrong ! It’s up to us to pay attention!!
It could be as simple as the meds you are taking or you are anxious about most anything that is going on right now. GO talk to your Doctor and let him run an EKG and see how your heart is doing. Maybe one of your meds need s to be changed. Stop worrying and go see what is going on.
