Thank you, I appreciate your concern 🙏
but yeah I’m pretty sure it’s just PCS in my case

Doctor has told me that it’s PCS and it seems consistent with my experience and has been happening to me for at least 10 years. Maybe it’s placaebo but lying down helps for me. I try not to take a deep slow breath cause it’s obviously really painful
edit: and “all the time” is an exaggeration, maybe once a month or less

Happens to me all the time, usually goes away after lying down even for just a moment or pounding on my chest. One time it didn’t go away though and lasted like 48 hours 😩

Anime is a really good tool if it’s something you’re into. Just have a dictionary pulled up if you hear words you don’t know. I’ve been studying Japanese for ~5 years now and the first 2 years were mostly just listening to anime and doing kanji flashcards. You can get surprisingly far with just anime, but yeah it can’t be the only tool. 勉強は頑張ってください 🙂
