I'm sorry to hear you're experiencing severe nerve pain on one side of your body along with dizziness. These symptoms can arise from various causes, including nerve compression or irritation, neurological conditions, infections, or vascular issues affecting the brain or nerves.

Given the complexity and potential seriousness of these symptoms, it is important to seek prompt evaluation by a neurologist. They can perform a thorough clinical examination and may recommend imaging studies or other tests to determine the underlying cause.

In the meantime, avoid activities that worsen your symptoms and ensure you have support if dizziness causes balance problems. If you experience worsening weakness, difficulty speaking, vision changes, or loss of consciousness, seek emergency medical care immediately.

Please consult a neurologist as soon as possible to get an accurate diagnosis and appropriate treatment tailored to your condition.To narrow down potential causes, we will need some more information.Could you please share your age and gender?
