What are the Symptoms of a Viral Nerve Infection?
Viral nerve infections, also known as neurological infections, present a wide range of symptoms depending on the specific virus and the part of the nervous system affected (brain, spinal cord, or peripheral nerves). Some common symptoms include:
- Flu-like symptoms: Fever, fatigue, body aches, and general malaise are often initial indicators.
- Headache: A severe headache is a common symptom, often accompanied by sensitivity to light (photophobia).
- Nausea and vomiting: Gastrointestinal distress can accompany other symptoms.
- Stiff neck (meningismus): This indicates potential meningitis, an inflammation of the membranes surrounding the brain and spinal cord.
- Mental confusion: Disorientation and cognitive impairment are possible, especially in cases affecting the brain.
More Severe Symptoms (requiring immediate medical attention)
- Hemorrhagic fever: Internal bleeding, a dangerous complication.
- Focal neurological deficits: Weakness or paralysis affecting specific areas of the body.
- Paralysis: Loss of muscle function, ranging from partial weakness to complete inability to move.
- Visual disturbances: Blurred vision, double vision, or other changes in vision.
- Convulsions/Seizures: Uncontrolled muscle spasms or jerking.
- Coma: A state of prolonged unconsciousness.
The specific symptoms can vary greatly depending on the virus and the location of the infection. For example, encephalitis (brain inflammation) might present with severe headaches, confusion, and seizures, while meningitis (inflammation of the membranes surrounding the brain and spinal cord) often causes a stiff neck and fever. Peripheral nerve infections might manifest as weakness, numbness, or pain in the extremities.
Some viral infections, such as the Zika virus, are known to cause Guillain-Barré syndrome, a serious condition causing progressive muscle weakness and paralysis. Herpes viruses can lie dormant for years before causing symptoms. Bell's palsy, a facial paralysis, is often associated with a viral infection.
