Advice still stands, get it looked at by a professional. I hold no medical qualifications and can’t poke, manipulate the area. Hobble your way to minors, take a book.
I'm Autistic, if I say something you find offensive, please let me know, I can guarantee it was unintentional.
I'll try to give my honest opinion but am always open to learning.
