[19F] Experiencing sudden, severe headache with dizziness and elevated heart rate

What might be happening

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

• Migraine: Migraines are a common type of headache characterized by severe, throbbing pain, usually on one side of the head. They can be accompanied by symptoms such as light-headedness, dizziness, and a rapid heartbeat. However, migraines usually come on gradually rather than suddenly.

  • Treatment typically involves over-the-counter pain relievers, rest, and avoiding triggers.

• Tension Headache: This is the most common type of headache and is often described as a constant ache or pressure around the head, especially at the temples or back of the head and neck. They are often related to stress, depression, or anxiety. However, they are not usually associated with an increased heart rate.

  • Treatment typically involves over-the-counter pain relievers and stress management techniques.

• Orthostatic Hypotension: This condition is characterized by a sudden drop in blood pressure when standing up, which can cause dizziness, fainting, and a rapid heartbeat. However, it's not typically associated with headaches.

  • Treatment usually involves lifestyle changes, such as drinking plenty of fluids and standing up slowly.

• Panic Disorder or Anxiety: These conditions can cause a variety of physical symptoms, including headaches, dizziness, and a rapid heartbeat. However, they are usually accompanied by feelings of intense fear or worry.

  • Treatment typically involves cognitive-behavioral therapy and medication.

What you can do

Given the sudden onset of your symptoms and the fact that you've fainted recently, it's important to seek medical attention as soon as possible. In the meantime, try to rest and stay hydrated. Over-the-counter pain relievers may also help with your headache.

What you should look out for

Seek immediate medical attention if you experience any of the following:

• A sudden, severe headache that's different from any you've had before
• A headache accompanied by a stiff neck, fever, confusion, seizures, double vision, weakness, numbness, or speaking difficulties
• A headache after a head injury, especially if the headache gets worse
• A chronic headache that is worse after coughing, exertion, straining, or a sudden movement
