Is it normal to feel nauseous weeks after a concussion?

It can happen, but it is a sign worth evaluating. Lingering nausea is often linked to problems with balance, eye movement, or neck function rather than the original injury itself. An evaluation can pinpoint which system is involved so treatment can target it directly.

Why do I feel sick when I read or look at my phone after a concussion?

Reading and scrolling require precise eye movements. After a concussion, those movements may not coordinate well with your balance system, which can trigger nausea, dizziness, or headaches. See our post on why screens make concussion symptoms worse.

Can a concussion cause insomnia?

Yes. Trouble falling asleep, staying asleep, or sleeping more than usual are all recognized concussion symptoms. Pain, headaches, and changes in how the nervous system regulates rest can contribute. If sleep problems persist, mention them during your evaluation.

Does poor sleep slow down concussion recovery?

Poor sleep can make recovery harder. When you are not resting well, symptoms like brain fog, irritability, and headaches often feel worse. Addressing the issues that disrupt sleep is an important part of a complete recovery plan.

When should I see a specialist for lingering concussion symptoms?

If nausea, sleep changes, or other symptoms last more than a few weeks or keep returning, it is a good time to schedule an evaluation. You can read more about typical concussion recovery timelines.
