Bell's Palsy

[AIDAPY]

Has anybody gone through physical therapy for retraining facial muscles? If so, how was the experience? I just had the bout two days ago and was not recommended to do it. However, my sister is a physician in another country and told me I should ask for physical therapy sessions immediately to prevent irreversible effects (better being proactive than waiting to have the problem and then probably having to require more sessions and at the end it will be more expensive. Any thoughts on that? Thanks
