What if motion sickness lasts for days?

Motion sickness starts when movement information from the eyes and balance organs does not match. Once the motion ends, the nervous system usually readjusts. Ongoing symptoms may instead reflect dehydration after vomiting, a migraine, an inner-ear disorder, medication effects, infection, or another balance problem. The pattern helps: spinning, hearing changes, headache, fever, or symptoms triggered by head position point to different possibilities.

Do not assume every episode is travel sickness, particularly if it began at rest or is happening for the first time. Record when it started, what movement preceded it, and whether you can eat, drink, walk, and concentrate.

Take gentle fluids in frequent small sips and choose bland foods as tolerated. Rest away from bright screens, rise slowly, and avoid driving until your balance and alertness are normal. Avoid alcohol and do not combine medicines for nausea without checking the label or asking a professional. Information about [Nausea](/symptoms/nausea/) and [Vomiting](/symptoms/vomiting/) can help you describe the episode clearly.

Get prompt medical care for inability to keep fluids down, very little urine, fainting, confusion, severe headache, new weakness, trouble speaking, double vision, chest pain, severe abdominal pain, blood in vomit, or difficulty walking. Arrange a routine appointment even without these signs when symptoms last for days or keep returning.

Tell your doctor about recent travel, rides, medicines, headaches, ear symptoms, and vomiting. Ask whether you need a balance or ear assessment and what prevention plan could help on your next journey. A [Travel Health Consultation](/treatments/occupational-and-travel-medicine/travel-health-consultation/) can address recurring travel triggers.
