Ask a Neurologist and Get an Answer ASAP
Welcome to Just Answer. I am an Adult Neurologist and was contacted to answer your question.
weakness in your pinky fingers that is symmetric does not suggest ALS
if could be seen in problems efffecting the spinal cord, or the nerves at the C7 or C8/T1 level
Would weakness in the left and not the right suggest ALS?
if you have diffuse twitching, then BFS or benign fasciculation syndrome should be suggested
if you only have weakness on the left
it can be ALS
but you need the evaluation
which includes the MRI and the EMG
ALS is a disease of the upper and lower motor neuron
so you should have some spasticity
a problem hopping?
no problem hopping
so it really is more like BFS, but you should not have weakness with BFS
it is also unlikely to have weakness in the pinky, and not the rest of your hand
unless you have a specific problem in your wrist
and none of that would explain the diffuse twitching
I didn't realize I had weakness in my pinky until the physical exam by the doctor today. He said that was the only weakness he saw.
do you have neck pain or shoulder pain?
well I am not sure of the reason for the pinky weakness
the EMG test is really what you need in this regard to answer that question
That's scheduled for Sept. I just wanted to calm my worries about ALS.
not to worry if you do not have spasticity as we discussed
ALS is 1:200.000 in your age group
I didn't ask the specific ALS question to my doctor, but he mentioned that after 8 months of twitching if it was indeed something very serious that I would present with more symptoms. Do you agree?
that is correct
after 8 months of twitching, you know if you have ALS from other issues
Thank you for your help!
you are welcome
