Your boobs will do all sorts of crazy things over the next few months. As long as its not unusually painful it probably just part of the process. I had aches, shooting pains, swishing, gurgling and all sorts 🙂 Im almost 13 weeks post op and am getting shooting pains on the underside of my boob again which I think is just the nerves as my boobs are beginning to have a bit more feeling there now. Just keep an eye on it and hopefully it will stop soon chick xxx
