Dear Kay:
It is always difficult to tell patients what they may have when we are not able to see the previous workup, examine the patient, and analyze the test ourselves. I would tend to believe that you do not have cramp
fasciculationMuscle twitching syndrome if there were no EMG correlates. The question, as you asked is what is the diagnosis if this entity is not happening to you. I am assuming that ALS has already been thought about, and the EMG together with the clinical history as ruled out ALS. In severe
myopathiesCardiomyopathy
Dilated cardiomyopathy
Hypertrophic cardiomyopathy
Muscular dystrophy
Peripartum cardiomyopathy
Restrictive cardiomyopathy, one can see
fasciculationsMuscle twitching with cramping, but the physicial exam and laboratory tests would rule this out also. Problems with electrolytes, and
endocrineEndocrine glands
Pancreatic islet cell tumor function might also cause
fasciculationsMuscle twitching and by lab test, these should be able to be ruled out.
By all the exclusions, it sounds that you have what are called benign fasciculations. These events are noted by fasciculations that come and go or can often be continuous. The fasciculations are usually made worse by fatigue, lack of sleep, and anxiety. They are not harbingers of ALS or other muscle disease. However, they are really psychologically draining. Watching your muscles twitch (fasciculate) is really bothersome. We have patients that have had these for years and some only a few days. It is very individual dependent. Some patients respond to low dose benzodiazepines, but many do not.
I hope this helps.
