Just to be sure, you had the EMG performed in the legs, where you were having the fasciculations?
And no significant weakness anywhere?
The EMG is the key here.
The fact that there was no issue with actual fasciculations seen on the EMG is important as that rules out motor neuron diseases.
And you don't have any significant weakness here.
The left arm/shoulder issue with soreness isn't going to be ALS either, as you would not get pain/discomfort from ALS.

Sure, you can upload the report here.
It's very unlikely that you would have had any progression over 5 weeks.
The EMG would pick up very subtle findings, perhaps even before you could notice them. And the fact that there was no actual fasciculations seen in the muscles that were "twitching" -- means ALS is ruled out.
That's only the first page, but nothing exciting there.
People can get fasciculations, particularly anxious people. Also smoking and caffeine can make it worse.
Every muscle tested was normal.
So you are fine.
Yes, it certainly has not developed in the past few weeks.
The muscles themselves tested as "normal", so no evidence of issues seen.
Yes, we have seen patients and had diagnosis of ALS before, but they clearly have abnormalities in strength and with their EMG, where there is widespread abnormalities seen in multiple muscles.
All of it looks fine.
Try not to worry, you're fine.
Yes, they are very normal, and many people have them.
A repeat EMG isn't going to help at this time.
If you notice progressive weakness in an arm or leg -- then EMG would be helpful.
It would be obvious to you -- you would have trouble walking, or holding onto things.
I'm a neurosurgeon that deals with arm/leg weakness all the time, and we order EMG tests to evaluate this -- and it is extremely rare (less than 5 people in 15 years) that I have diagnosed ALS.
There not much specific treatment. Because you don't have any signs of radicular issues (nerve issues from the spine) on your EMG, this will just get better with time.
Random fasciculations aren't worrisome.
Calf fasciculations are a bit more curious, but your EMG didn't show any concerns in the gastrocnemius muscle. But perhaps considering MRI of the lumbar spine to rule out a "pinched" nerve could be done.
EMG rules out ALS.
A pinched nerve at the L5-S1 could cause it in both calves.
