Sorry for my ignorance but isn’t it normal for your heart rate to go up when u stand up quickly?

And by the way I can work out, and it’s going on fine for me. But whenever I go out I’ve been feeling weak, faint and just overall bad like I need to hold my chest as if something was weird. Going to see a doctor about it once I get my insurance done. Went through some pretty messed up shit so my nervous system is kind of messed up and I’m in process of getting better… maybe there’s a correlation. I don’t think I have POTS but the feeling faint once going out is very odd and a person suggested this. Again, sorry for my ignorance… I check pulse 10 mins after standing up as a DYI test and Hr goes up by like 10 which seems okay?… Oh and been dealing with bad anxiety went through some panic attacks ( the one that makes u go to the ER ) but things are getting slightly okay. Oh and I’m diagnosed with ADHD but refused the meds, because I wanted to. Heart tests echo-blood test-ekg came back okay.
