Is there a reason my stomach could still be hurting after throwing up yesterday?

I’ve thrown up before and had my stomach hurt for a few hours afterwards, but this time it’s been over 36 hours. I’m not exactly sure if I had food poisoning this time, or if I just had really bad indigestion, but for some reason my stomach keeps lurching every hour or so.

Is this somewhat normal for someone recovering from what happened, or do you think my body is reacting to something still inside me?
