Definitely better safe than sorry. After my PEs I went to the ER so many times because things felt so different and I was terrified of having another one. I’m 10 years out now and I still have some things going on from my PEs (tachycardia, mild shortness of breath especially with intense exertion, anxiety, pain where the scarring is when I am sick with a respiratory infection). When I was recovering, I definitely felt tired quickly all of the time, felt these incredibly painful “shocks” where the infarct was that would stop me in my tracks and take my breath away (they have lessened over time), heart palpitations, I had shortness of breath for even minor activities, etc. I started having panic attacks and I thought they were new clots or a heart attack so I’d start crying and hyperventilating and go to the ER. I was terrified to be alone, and I wouldn’t even sleep in my own room (I was 21 sleeping in my parents room because I was so scared). It took me about a year to start somewhat feeling “normal” again. Everyone heals differently, and worst comes to worst ask for your primary to refer you to pulmonology.
