About four or five months ago, I was also diagnosed with bell's palsey. It came on very sudden and I didnt know what caused it either. They also gave me the steriods, make sure you take them. I didn't think it would ever go away, but by taking the steriods and just trying to relax my case of bell's palsey went away in about three to four weeks. If you need any other information feel free to email me.
