Vomiting is the uncontrollable reflex that expels your stomach contents through your mouth. Nausea and vomiting on its own is rarely a cause for concern. Many conditions and diseases cause nausea and vomiting such as motion sickness and emotional distress. It can be caused by something more serious such as a brain injury putting pressure on the brain. Over-the-counter medications and home remedies will relieve most cases of nausea and vomiting. However, vomiting due to pressure on the brain will disappear once surgery has taken place. Recovery from surgery usually takes a few days, unless there are complications. In some cases, the hematoma can come back and has to be drained again.
