I can certainly vouch for the breast twinges, pains, hyper-awareness, discomfort, and layers of healing. And the one cyst that had been my nemesis for years. Aargh! The last to heal, of course. The cysts that were the most recent, healed first. That final cyst, felt so deep near my chest wall, the memory hasn't gone away. I can still pinpoint exactly where it'd be, if it still was. I love my iodine! :)
