I swallowed heaps of seawater and got sick. This was 3 days ago, and I'm still sick to my stomach. Is this ok?

I took my second surfing lesson here in Australia on Thursday. Mind you, I'm from the US on an exchange. Anyways, It was loads of fun till I wiped out many times, ingesting saltwater while doing so. Later that evening, I vomitted because of the over-ingestion. It's Saturday now, and I'm still feeling sick to my stomach. Is this normal, or should I go see a Doctor?
