The first time I binded mine tight, they were sore a couple days.. and tingly. I was concerned because I had even abided by the 15 minute rule. After speaking to a couple people, they confirmed that this was normal. Whether or not it's right, I don't know. Also, I would think the soreness would be elevated if the breasts were played particularly hard.

Since then, mine haven't had the lingering effects as long, if at all.
