[46F] With sudden headache, stiff neck, and lethargy post-COVID

What might be happening

Based on the symptoms you've described—sudden severe headache, stiff neck, sore shoulders, fever, and increased sensitivity to sound—there are a few serious conditions that could be causing your symptoms:

1. Meningitis: This is an infection of the protective membranes covering the brain and spinal cord. Symptoms often include a sudden severe headache, stiff neck, fever, and sensitivity to light or sound. Meningitis can be life-threatening and requires immediate medical attention.
2. Subarachnoid Hemorrhage: This is bleeding in the space between the brain and the tissues covering the brain. It can cause a sudden, severe headache, neck stiffness, and sensitivity to light or sound. This condition is also a medical emergency.
3. Encephalitis: This is inflammation of the brain, often due to an infection. Symptoms can include headache, fever, stiff neck, and sensitivity to light or sound. This condition also requires prompt medical treatment.

What you can do

Given the severity and sudden onset of your symptoms, it is crucial to seek immediate medical attention. Here are the steps you should take:

1. Go to the Emergency Room: You should go to the nearest emergency room as soon as possible. If you are unable to get there yourself, ask someone to drive you or call an ambulance.
2. Call 911: If you are alone or if your symptoms worsen, such as experiencing confusion, loss of consciousness, or severe headache, call 911 immediately.
3. Avoid Self-Medication: While waiting for medical help, avoid taking any more medications unless advised by a healthcare professional.

Please remember that I am not a doctor, and it is essential to seek care from real health professionals to receive a formal diagnosis and appropriate treatment. Your symptoms are serious and require immediate medical attention.
