Lyme Disease — 20 Signs To Watch For

6. Facial Palsy

Between 5% and 10% of people with Lyme disease develop facial palsy during the infection. If the paralysis is bilateral, this points even more strongly to Lyme disease.

Very few disorders cause facial nerve palsy on both sides of the face; when facial nerves are affected, individuals experience weakness or immobility in the muscles. Treatment for facial palsy generally takes around three months for complete recovery. In some cases, however, it may take a year to 18 months before the nerves completely regenerate.
