fasciculation

[sogil]

i'm 36 years old and i have constant and almost all day widespread fasciculation for about 13 month without muscle weakness, or muscle atrophy. the fasciculation are mostly widespread exept for several episode of fasiculation in spesipic muscle (including one time of the tip of the tongue)that lasted for up to 48 hours.

2 emg,bllod test' mri and neurological exam were normal exept for isoleted finding in one muscle (mild neurogenic changes in a single muscle without evidence of denervation)and increase reflex

i have read that Benign fasicualtions tend to be rare, spread out over the body and tend not to be progressive. In neuromuscular disease, fasiculations are more likely to be localized, more frequent and occur non-stop.
i am very worried ,how many times do fasciculation accur due to bfs? - i have it almost all day for 13 mount now and not just several times a day ?? does it mean that i can develop als??do you think i may have mnd??

First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.    
   The symptoms that you describe are unlikely to represent ALS (amyotrophic lateral sclerosis/ Motor neuron disease), but I would recommend a complete workup.  Fasiculations can be seen in normal people, in metabolic derangements, after exercise, after viral infections and with some neuromuscular diseases.  It is true that ALS/MND generally presents focally with weakness/atrophy and fasiculations.  However, with widespread fasicualtions without weakness or atrophy (especially with a normal EMG), make benign fasiculation syndrome much more likely.  I would recommend that you have an MRI of your spine (with ALS protocol) and an EMG by an ALS expert at a major academic institution.
I hope this has been helpful.

Sogil,
  I strongly recomend that you also look into stress disorders depending on your stress level. These twitches are non-specific and since they occur in the absense of other symptoms I doubt that there is anything to worry about in the area of the serious neurological conditions that can cause them such as ALS, MS, to name a few. This is further clarified in your normal studies of the bain, et al.
  Many believe that aside from stress dietry issues can be to blame such as aspartame. As well, you could have heavy metal poisoning, and so on. The answer does not always lie in the obvious.

Good Luck!
