I m a healthy 35 years old woman, Christmas Eve I fell on my rib (under my right breast) and heard a pop. Next day i was fine, no pain, nothing but 2 day later i woke up with a stabbing pain at this same spot and still have it . I feel relieve when i sleep on that side, it seems to relieve my pain. But if i touch a single point it hurts like crazy. What could it be? I have no bruise, i don t see any bump and it feels all in place when i touch.
