People enduring Bell's palsy may also apply physical therapy on the facial muscles, as it may facilitate in stimulating the nerves affected by this condition and also assist in sustaining or improving the muscle tone. Besides, augmenting blood circulation, massaging the muscles of the face may also assist in unwinding the facial muscles that have been contracted owing to Bell's palsy. In addition, your therapist may as well recommend exercises for the facial muscles for the patients to practice at their home with a view to sustain the tone of the facial muscles.
Roughly, from the studies, it seems that if you do not take steroids you have about a 15 in 20 chance of full recovery of the nerve function. But, if you take a steroid medicine, you have about a 17 in 20 chance of full recovery. So, taking a course of steroids does not guarantee full recovery of the nerve function. However, it increases the chance of full recovery compared to no treatment. You should start the course of steroids as soon as possible after the onset of symptoms; ideally, within 72 hours of symptoms starting. They may not have much effect if they are taken after this.
