In some cases, Bell’s palsy recovery plateaus because the nervous system and muscular coordination have not fully returned to balance.
Even when the nerve has healed, facial tightness, synkinesis, muscle weakness, or abnormal movement patterns may remain.
Stress on the nervous system, emotional strain, and compensation patterns in the face and body can also affect how recovery progresses.
When these factors are not addressed, healing may slow down or stop before full recovery.
