Bell’s palsy is often a standalone condition that resolves within a few months. However, it may be a symptom of a more serious underlying condition in rare cases. Here are some possible situations that may cause Bell’s palsy:

• Lyme disease

• HIV/AIDS

• Sarcoidosis

• Tumors in the head or neck

• Diabetes

• Hypertension

• Multiple sclerosis

If you’re experiencing Bell’s palsy symptoms and are concerned about an underlying condition, it’s essential to consult with your doctor. They can perform tests to rule out any more severe conditions and provide you with an accurate diagnosis.
