Hi. This is new for me, but here goes... I am 49 and had been very healthy. About 6 weeks ago, I contracted a nasty viral illness with perisistent diarrhea and some respiratory symptoms. The same day I got sick, I started having fasciculations different places in my body. The viral illness lasted at least 10 days, and the fasciculations are continuing, although maybe a bit milder. About a week after the illness set in, I also started experiencing vibrating in my feet, cramping various places throughout my body, and sometimes felt like my entire body was vibrating. I had a tremor for several days, which went away. The vibrating has improved, although I still have it in my feet. One interesting side note... I had a nasty viral illness in my twenties, which left me with the vibrating all over my body for a while, but particularly in my feet. I had stiffness in my joints and the vibrating sensations for over a year. I've been tested several times for Lyme and various things, but was always negative. Since that illness, sometimes when I get sick the vibrating comes back, but milder and goes away after the illness does. Never had fasciculations until this illness. I am going to see a neurologist in November, and am pretty sure it's BFS, since my experience sounds similar to what others of you have experienced. Just thought I would comment because it's very strange indeed. I, too, was concerned about ALS. On a side note, my husband was initially diagnosed with ALS when he was 40, but has a much rarer condition called multi-focal motor neuropathy, which is treated with IVIg.
