Vitamin B12 will help with any nerve damage and irritation in your face. 500mcg 3 times a week by injection or 500mcg per day in tablet form. The injections are the best if you can get them. I have seen this treatment help with even very established (old) cases of bell's palsy.
Also take 500 mg Wormwood in the morning taken with one Aleve - another 500 mg at night with one Aleve. Do this for 2 weeks on and two weeks off. This will stop the nerve pain. When the pain ends - stop the Wormwood and Aleve alltogether.
Valerian root at night will help you sleep. It can be taken longer than the 2 weeks. I hope this helps :)
