M.L.
My friend had bells palsy while she was pregnant as well (the baby was fine), and my fil has had it twice, each time it was a different side of his face which is very rare.
The duration varies, per person... as so does healing. My friend recovered fully within a few months, but my fil still has a hard time moving some mouth muscles and still has dry eyes and it's been 10 years, but it's barely noticeable unless you look really hard.
I believe the pain and paralysis lasts just a few weeks though, to return to normal can be several months.

Here are some things you can do at home to help with the pain:
* Protecting the eye you can't close. Using lubricating eyedrops during the day and an eye ointment at night will help keep your eye moist. Wearing glasses or goggles during the day and an eye patch at night can protect your eye from getting poked or scratched.
* Taking over-the-counter pain relievers. Aspirin, ibuprofen (Advil, Motrin, others) or acetaminophen (Tylenol, others) may help ease your pain.
* Applying moist heat. Putting a washcloth soaked in warm water on your face several times a day may help relieve pain.
* Doing your physical therapy exercises. Massaging and exercising your face according to your physical therapist's advice may help relax your facial muscles.
Although there's little scientific evidence to support the use of alternative medicine for people with Bell's palsy, some people with the condition may benefit from the following:
* Relaxation techniques, such as meditation and yoga, may relieve muscle tension and chronic pain.
* Acupuncture, placing thin needles into your skin to relieve pain, may stimulate nerves and muscles, offering some relief.
* Biofeedback training, by teaching you to use your thoughts to control your body, may help you gain better control over your facial muscles.
* Vitamin therapy — specifically B-12, B-6 and zinc — may help nerve growth.
