on-going fasciculation in same muscle for 2 years
Index finger and thumb. I have stiffness. I don't notice weakness.
I originally went to chiropractor who said I have an issue with my neck. But other than aching pain from neck I don't have other symptoms like pain down the arm etc.
If this has been going on in the same muscle group for 2 years without progression, this is reassuring. :-)
Fasciculations are typically the result of irritation or hyperexcitability in the motor unit. This can result from numerous causes, most of which are benign.
The chance of it being related to a pinched nerve in the neck is pretty low, but not zero.
have you ever injured your neck?
Most serious neurodengenerative conditions progress steadily....so one would expect worsening of the condition over 2 years...either greater severity of the existing symptoms or progression to other motor units around the body.
This is a common site for benign fascics because it is being used all the time (at least when we are awake) and the risk of overuse, or strain, or injury is pretty high.
A C5/6 cervical lesion would be expected to cause symptoms a bit higher up the arm.
If there were ongoing damage in the C6 nerve, for example, one would expect some forearm involvement over a 2 year period, probably weakness and even atrophy.
have you had a cervical mri?
This would provide an added layer or reassurance, if normal.
Ah yes...you have Googlitis! :-)
another option would be to get nerve conduction tests (i.e EMG and NCV).
this would reveal any worrisome features in the nerves or muscles.
That is correct.
and when it does occur, it tends to be more widespread
you would expect progression...
increasing severity, increasing frequency, increasing number of affected sites, new symptoms such as weakness or atrophy...those types of things.
yes, that's generally the case in progressive neurological diseases...certainly by 2 years.
yes, or elsewhere in the body.
i think it would helpful for you to get one more layer of reassurance...nerve conduction testing is the way to go, in my estimation...though it is very likely to be normal.
The stiffness is often a result of the underlying process causing the fascics...either injury or overuse or hyperexcitability.
bfs is usually more widespread...but it is a spectrum disorder ranging from very mild and localized to very severe and widespread.
yes, overuse can be an important factor...as can stress...fatigue...poor sleep...imbalanced diet...electrolyte imbalances...too much caffeine, etc
i think this is correct.
you're welcome...glad to help...bfs does not normally involve any loss of subq fat. :-)
