[21F] Experiencing head swelling, headache, and blurry vision

What might be happening

Based on the symptoms you've described, here are some possible conditions:

• Temporal Arteritis: This is an inflammation of the arteries in and around the scalp. This condition often presents with a tender, swollen temple, headache, and sometimes changes in vision. It is more common in individuals over 50, but it can occur in younger people.

  • The standard test for this condition is a biopsy of the temporal artery. Treatment typically involves high-dose corticosteroids.

• Migraines: Given your history of migraines, it's possible that your symptoms are related to a particularly severe or unusual migraine episode. Migraines can sometimes cause visual changes, dizziness, and neck stiffness.

  • Treatment for migraines often involves pain relievers, triptans, ergots, anti-nausea drugs, and preventive medications.

• Infection: Given your recent sore throat and ongoing diarrhea, it's possible that you have an infection that's causing your symptoms. Some viral infections can cause headaches, neck stiffness, and dizziness.

  • Treatment would depend on the specific type of infection, but may involve rest, hydration, and over-the-counter or prescription medications.

What you can do

You should seek medical attention as soon as possible. Your symptoms, particularly the combination of headache, visual changes, and neck stiffness, warrant a prompt evaluation by a healthcare provider. They can provide a formal assessment and order relevant tests if necessary.

What you should look out for

Please seek immediate medical attention if you experience any of the following:

• Sudden, severe headache
• Sudden loss of vision or double vision
• Difficulty speaking or understanding speech
• Difficulty walking or maintaining balance
• Fever or chills
