My mother was 1st diagnosed with B.P.about 1969..after treatments of muscle relaxers face massage w/heat it went away. It came back again in the approx. 1978. Again got better. The last time she got it in the late 80's her face never went back to normal, always the same sideof the face...She's been to Specialist. the Mayo clinic..accupuncturist, etc. She sees to believe it is from drafts, air-conditionng, and also from severe emotional stress. She is 85 now and has learned to live with this disfiguring disease. People always ask if she has had a stroke. It has affected the eye on that side. It doesn't open & close voluntarily. I do believe it could be in the work-place environment. My Mom was working in a factory when the 1st attack came. Maybe it would be wise to contact OCEA (not sure of the spelling) you can remain anonymous. Good Luck! Take Care.
