Headache on the top right of the head

Pain in one area does not identify one diagnosis. Tight scalp, neck or jaw muscles can create pressure that spreads toward the crown. Migraine may cause throbbing or pulsing pain, light or sound sensitivity, nausea, or a need to rest. A blocked nose or facial pressure can occur with Allergic Rhinitis, Chronic Sinusitis or a Common Cold. Fever and body aches may accompany COVID-19 or Dengue Fever. Dehydration and Heat Exhaustion are additional possibilities, especially after sweating, outdoor activity or limited fluid intake.

Move to a quiet, cool place and rest your eyes. Sip fluids, eat if you have missed a meal, and loosen anything pressing on your head or neck. Gentle neck movement may help when the pain follows prolonged screen use or an awkward position; stop if it increases pain. Note when it began, how severe it feels, what preceded it, and whether fever, vomiting, vision change or weakness appears. Use only medicines suitable for you and follow the label; ask a pharmacist if you take other medicines or have a health condition.

Seek emergency help for a sudden, severe headache, new weakness or numbness, trouble speaking, confusion, fainting, seizure, severe neck stiffness, repeated vomiting, or a new headache after a head injury. Get urgent medical assessment for severe headache with fever, a new vision problem, or marked eye pain. Arrange a clinician review if the headache keeps returning, changes pattern, disrupts sleep or daily activities, or does not settle with simple measures.

Could the location and timing fit tension, migraine, sinus symptoms, dehydration or heat exposure? What warning signs should I watch for? Which pain-relief options are appropriate with my medicines and health conditions? Should I keep a headache diary or have my eyes, blood pressure, neck and neurological function checked?
