ALS does not move that quickly, and 'fasciculations' in the absence of objective fixed muscle weakness and wasting is very unlikely to be ALS. Also, if it is widespread this is more unlikely to be ALS also, unless late in this disease. There are many other causes that are more common such as an overactive thyroid gland, pinched nerves, certain medications, as a benign syndrome, other spinal cord problems etc.
The hand weakness etc should be evaluated by a neurologist or physician to see if there is any fixed neurological problem in the physical examination, and to organise any relevant testing. Symptoms in three different limbs is hard to localize to one area of the nervous system, but can occur with problems in the brainstem or upper spinal cord,, and this should be evaluated promptly, for example with MRI and MR angiogram as you are doing.
Good luck
I just wanted to share my own reservations about my health fears in hopes that it will make you feel better.
Take care and good luck. I will keep you in my thoughts and prayers.
I will say one other thing, the more you read about it on the internet, the worse the symptoms will get, so be careful!
Take care and good luck.
