[28F] Experiencing severe, sudden-onset headache with neck stiffness and light sensitivity

What might be happening

Based on the information you've provided, the possible causes of your symptoms include:

• Migraine: This is a type of headache characterized by severe, throbbing pain usually on one side of the head. It can be accompanied by symptoms such as sensitivity to light and sound, nausea, and vomiting. However, you mentioned that you and your family have no history of migraines, which makes this less likely.

  • Treatment typically involves pain relievers, anti-nausea medications, and preventive medications to reduce the frequency and severity of migraines.

• Tension headache: This is a common type of headache characterized by a dull, aching sensation all over the head. It is often described as a feeling of a tight band or dull ache around the head or behind the eyes. These are often related to stress, depression, or anxiety. Over-the-counter pain relievers such as aspirin, ibuprofen, or acetaminophen can be effective.

• Cluster headache: This is a rare type of headache that occurs in cyclical patterns or clusters. It is one of the most painful types of headache, with intense burning or piercing pain behind or around one eye, and may be accompanied by redness, swelling, or tearing of the eye.

  • Treatment typically involves medications to lessen the severity and frequency of the cluster headaches.

• Sinusitis: This is an infection or inflammation of the sinuses, often caused by a viral or bacterial infection. Symptoms can include headache, facial pain, and nasal congestion. Since you mentioned having a recent ear infection and some blood when you blow your nose, this could be a possibility.

  • Treatment typically involves antibiotics, decongestants, and pain relievers.

• Medication-overuse headache: This type of headache occurs when medications are taken too frequently to relieve headaches, leading to a rebound headache. It's less likely in your case as you've only taken Tylenol once.

Please note that this is not an exhaustive list and other causes may be possible.

What you can do

Given the severity and sudden onset of your symptoms, it's important to seek immediate medical attention. While waiting for medical help:

1. Try to rest in a quiet, dark room.
2. Stay hydrated.
3. Avoid activities that worsen your headache.

What you should look out for

Seek immediate medical attention if you experience:

• An abrupt, severe headache like a thunderclap
• Headache with fever, stiff neck, mental confusion, seizures, double vision, weakness, numbness, or speaking difficulties
• Headache after a head injury, especially if the headache worsens
• A chronic headache that is worse after coughing, exertion, straining, or a sudden movement
• New headache pain if you're over 50
