Definitely go to the ER just to get some scans done. You dont truly know if anything did rupture within..hopefully and probably not, but, given your pain, its really best to get your stomach looked at. Please go, Deepblack, and maybe they can also give you some meds for your bruising/pain.

You may have internal bleeding or organ injury. Go to the hospital immediately, please.

If it gets worse, or doesn't start getting better, do go and get checked out. Please.

Off to the ER, now... you need to be checked over ASAP.

A tip to the ER or urgent care facility seems to be in order. You may have bruised or rearranged some internal organs. The lower abdomen doesn't have that protective cage called the ribs like the upper body does.

How did you get injured?

Oh gosh, get some rest, sleep is when your body heals

What the hell happened?

I am really sorry. What happened?
