ugh, OUCH! You were looked at and they didn't do anything invasive. I would guess they are right about the deep bruise. I'd take ibuprofen rather than Tylenol personally (I think it works better for pain relief). If it doesn't subside, see your ob/gyn rather than the imaging center. Sorry. Mammos can be a little painful but that is a bit much to bruise you like that! New tech? I'd make sure you complain about it!! good luck
