Thanks for your input.Sorry to hear your problem.
Fasciculations,(twitching) as you probably already know, can be benign or pathological.
Benign ones - such as in people who are very active physically or work out a lot and occur without any other associated symptoms. Pathological ones usually occur in association with other neurological symptoms such as muscle fatigue
, pain, weakness, etc.
If they occur as frequently as you described, they should have been picked up on EMG either spontaneously or after being elicited.
Well, it sounds like you have fasciculations- which are local involuntary muscle twitching. These can be caused by MANY different things:
Drug overdose (caffeine)
Drug side effect (such as from diuretics, corticosteroids, or estrogens)
Benign twitches- - triggered by stress or anxiety
Electrolyte abnormalities (calcium and potassium)
Nervous system conditions that can cause muscle twitching:
Damage to the nerve that leads to a muscle
Spinal muscular atrophy
Weak muscles (myopathy)
I would advise you complete evaluation by examination(physical),investigation,,,,,followed by disease specific treatment.
As your symptoms are there for about year,it need complete evaluation.
