I was so sorry to read about your problems, and will keep you in my prayers and send loads of healing energy your way.
I had a similiar thing happen about 16 months ago, it turned out that it was not Bell's Palsey, I was bit on the face by a spider, tiny bite, then came the high fever, for 8 days, the facial parlysis with drooping lip, and when I woke up one morning and could barely walk, I decided it was time to get to the doctor. Doctor said it was Bell's Palsey, then in discussion with him, and showing him the tiny spot on my face, he agreed with me that it could be the spider bite. I was fortunate becasue I had not taken antibotics for 30 years, so the Doctor put me on mega doses of antibotics and after 3 weeks I was back to normal.
I usually do not post things on the board, but felt that this may help someone else in the future. I live on top of a mountain, surrounded by trees, and in 22 years of living here, I have become immune to most bites, however the brown recluse spiders have become very bad in Pa. Again my best to you Pat Feick
