I don’t think a reason was given… it just stopped after he lost his memory.
I think it's bc he's not actively enduring his trauma (idk how to word it) I mean like he's out of the situation where he was actively being exploited and abused, so his body tried to rid the trauma by 1. Forgetting and 2. Getting rid of the pearls, but now even though his memory of his trauma are back, his physical "symptoms" remain gone. And it makes sense because the pearls were the reason he was being abused in the first place . Tell me if I'm confusing you more
Oh! I got it! Thank you so much guys ٩(๑❛ᴗ❛๑)۶
Why the pearls dont come out anymore? I forgot
