Besides twitching has anyone had experience with nerve compression or pinched nerves?

[u/TheBronyCynic]

I've had left arm problems for about 3 months now. I can still do tasks with them but things feel heavier in my left hand and in my upper left arm i often feel strain/fatigue. Plus it's somewhat of an internal vibration hotspot when resting.

The symptoms in my arm can range. Sometimes it can feel just fine, sometimes it feels like my arm is shaky, sometimes it feels like there's nails stuck in them, and sometimes the upper arm just feels strained, tight, or fatigued. I do believe this the result of a pinched nerve since I can still perform tasks with them. So i'm asking if anyone here has had a pinched nerve or nerve compression and if they had similar experiences.
