[18F] Experiencing migraines, dizziness, and transient loss of vision post-fainting episode

What might be happening

Based on the information you provided, here are some possibilities:

• Migraine: This is a type of headache characterized by severe pain, often on one side of the head, and can be accompanied by other symptoms such as visual disturbances and nausea. The tightness you described in the back of your head and the severity of your headache could be indicative of a migraine. However, migraines typically do not cause fainting or shaking.

• Orthostatic Hypotension: This is a form of low blood pressure that happens when you stand up from sitting or lying down, and it could explain your dizziness and blacking out. However, it does not typically cause headaches or shaking.

• Seizure: This is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in your behavior, movements or feelings, and levels of consciousness. The shaking you experienced when you fainted could be indicative of a seizure. However, seizures are usually followed by a period of confusion, which you did not mention.

• Panic Attack: This is a sudden episode of intense fear that triggers severe physical reactions when there is no real danger or apparent cause. It can cause symptoms such as shaking, shortness of breath, and numbness or tingling sensations in the extremities. However, it does not typically cause headaches or blurred vision.

Please note that these are just possibilities and not a definitive diagnosis. It's important to consult with a healthcare professional who can evaluate your symptoms and medical history in person.

What you can do

Given the severity and range of your symptoms, it's important to seek medical attention as soon as possible. Here are some steps you can take:
