Als early on set?

Hi there!

I have been experiencing for the past 8 weeks tingling, numbness in pinky and ring finger, inner forearm, progressive weakness in hand (yet no objects dropping or any similar issue.) I even had some improvements by being able to reuse keys, button a shirt, etc... after taking naproxen.

It also started with pain in shoulder.

I had an MRI showing osteophytic disc bar causing mild spinal canal stenosis with moderate left foraminal stenosis in C7-T1.

My physio seems concerned because my symptoms seem to match medial nerve but also ulnar nerve, but if I understand correctly C8 distributes to these nerves? He also said my trapezius area, forearm and wrist feel very tight.

I also see fasciculations in the thenar area in the affected hand, but also the other arm and leg.

Any light on this? Do you think this can be als early on set?
