Headache on the right side of the head and eye

Migraine can cause one-sided throbbing pain with nausea or sensitivity to light. Congestion, facial pressure, or a recent cold may make sinus-related discomfort more likely. Eye strain, an uncorrected vision problem, or prolonged screen work can add pain around the eye, but location alone cannot confirm the cause.

Pay attention to a red eye, blurred or reduced vision, halos around lights, marked light sensitivity, swelling, or pain when moving the eye. Fever, body aches, or poor fluid intake may accompany infections, dehydration, or heat exhaustion. Anxiety and tension can intensify pain without explaining every new eye symptom.

Pause screen use, rest in a dim room, and drink fluids slowly. Avoid rubbing the eye. Record whether the pain is pressure, throbbing, stabbing, or burning; whether it comes in episodes; and whether light, movement, congestion, or heat affects it.

A pharmacist can advise on a suitable labelled pain option after checking your health and medicines. Do not borrow prescription eye drops. Arrange an examination if this is a new pattern, keeps returning, follows a change in vision, or does not improve with simple measures.

Seek emergency care for sudden severe head or eye pain, new loss of vision, a red painful eye, unequal pupils, confusion, fainting, weakness, numbness, trouble speaking, or a seizure. Urgent assessment is also needed after an eye or head injury.

Get same-day medical advice for fever with eye swelling, repeated vomiting, severe light sensitivity, or rapidly worsening pain. Do not drive yourself if your vision or alertness is affected.

Ask whether your symptoms need an eye examination or neurological assessment, whether vision or screen habits may contribute, which treatments are safe with your medicines, and which changes should trigger emergency care.
