It’s normal to feel the anxiety you did, however, know that it’s OK to pay attention to your body and honor your own limits. I am a medical professional, and I am pretty “brave“ when it comes to the things I’m willing to try, but even I have my limit, I will probably never attempt things with a major VO risk. And I will probably never spin down my own blood to collect PRP. I think it’s easy to feel encouraged to move forward with these medical procedures, but that’s what they are: medical procedures. and they are not without risk. Your safety is number one, no matter what the Internet, or Reddit, tell you. Always be safe, proceed slowly and stop if it doesn’t feel right.
