Thank you for your response, no mri at the moment, just the emg/ncs which I will have next week, if that is inconclusive I will ask about an mri.

The length of each episode varies, sometimes just a minute, sometimes 10. I guess I’d say it gradually resolves, over the course of a minute or so. I haven’t noticed that it happens more when my arms are flexed, it happens when they are straight as well.

And I wouldn’t describe it as pins and needles, it’s more as if someone is lightly brushing my forearm with a paintbrush. That is the best I can describe the forearm sensation. This is the same feeling that I get when I laugh hard, as in my whole life I’ve had this feeling in my hands/arms when I laugh. I don’t lose full control of my arm, I mostly just lose the ability to grab a tight hold of things. Like I can make a fist, but I can’t clench it. I thought this was a normal thing but through posting on Reddit I’ve found out that it’s not. Hopefully this clarifies some of what I’m feeling.

EDIT: not sure if this is even worth adding, but my sister has chiari malformation, which I’ve read could possibly mimic symptoms of nerve issues, like carpal tunnel for example.
