Tim,

Welcome to NeuroTalk.

If the minor nausea is your only problem, I suggest you just watch carefully. If it gets worse, then see a doctor. If other symptoms manifest, like extreme headache, difficultly balancing or with motor control, get to a doctor. An urgent care clinic is usually good enough. No need for the ER unless you start to vomit or get extreme symptoms like the extreme headache, balance, etc. If that happens, have someone drive you.

Most like, this symptom will start to fade over the next week or two.
