I've not posted in 4 or 5 months. I know exactly what you're talking about. I can't hold any muscle in a contracted static position without a tremor, and yes its most noticeable in my fingers, mandible, quads, and right tricep. But in a larger sense--function is not affected. No clinical weakness. I noted my first fasciculation 17 months ago which quickly spread to every muscle in my body-toes, feet, legs, torso, arms, fingers, scalp, ears, *beep*, and even my middle ear which created a drumming sound. Had the buzzing, vibrations, etc, which were constant and unrelenting, even during my sleep according to my wife. Seen by the appropriate physicians with the usual tests--all negative. The fasciculations persist pretty much 24 hours a day; although not with the same intensity. Definitely worse after exercise and/or when I/m fatigued. The bigger annoyance is the rippling muscle and tremor on contraction, including inability to hold fingers in the aforementioned static position. I was seen by a fine neurologist in April (3rd visit) and we agreed follow-up visits were not indicated. I know enough about ALS to understand I absolutely do not have that disease. Having said that, I know that BFS is a real neurological or metabolic condition, and benign only in the sense that it is not ALS or any of the usual neuro disorders. But it is worrisome, annoying, and sometimes fatiguing. Vitamins, diet, supplements--tried them all without too much success. Refused the heavy medications offered by neuro. Don't need those side effects too. As a final note, I've been an exercise fan all my life, I'm 57, and last week I set an impressive personal best time for my 50's on a 17 mile bike ride, *beep* near killed me, but it sure felt good, and I know that after a year and 1/2 of symptoms, I sure couldn't have accomplished that with any serious neurological disease. Hang in there. Carpe diem. Keep pushing.
