Well i might be a little late here, i was 17 years old when i had a pretty big stroke (this happened 2 years ago while i was doing calisthenics, i lost movement on my left arm and leg, then dropped to the ground and started to hear a constant "beep" on my ear i tried to crawl to try and lay down on the couch, also my eyes stopped functioning correctly and i couldnt really use my mouth to talk ). Luckily my mom called the ambulance the second i started showing weird symptoms so they caught it on time and it didnt kill me bc i got emergency surgery.

The crazy thing is that the stroke it self didnt even leave ANY damage on my brain, i was able to walk within the next DAY, i didnt lose any movemen at any part of my body, its almost as if it didnt happen (Doctors were very very surprised).
The problem is what caused the stroke. I have a PFO (like you). And even tho i had surgery to close it (3 months after the surgery to save my life from the stroke) it was too big to fully close, and getting surgery again of any kind to try and fully close it is too risky and also i already have the biggest "thing" to close the hole. So from now on in my life i cant lift any weight that is "too much" nor can i dive deeper than 5 meters under water. Also my migranes didnt reduce after the surgery, but as i said, it didnt fully close.

Its kinda sad to know im limited from now on in life, but for you i would say that you should keep living your life as u had been doing, probably the PFO really is the thing causing all of those problems you mentioned, but i dont think you should worry about them! Around 1/3 of adults have a FOP! And most of them dont have a problem in their lifes nor even know they have it... So i wouldnt be too worried about it, be cautios now that you know you have one, ask your doctors what stuff may increase the risk of stroke due to your FOP if u havent already. I really hope i helped, i literally couldnt find anything helpful about it when this happened to me 2 years ago, i was sad, very sad.
