No they don't hurt at all. I've even hung little ornamental jewelry accessories and around Christmas time I like to put little bells on the one on my balls and I always joke, Jingle BALLS. LOL. It's funny cuz other people will hear the jingling and be looking around to see who has bells on. Lol. I laugh a lot. Good question. Feel free to ask me anything . I've even had a small chain necklace attached to them both together
