Yes...and yet, no.
The brain controls the muscles that constitute your forearm. It’s not impossible to imagine that some sort of central nervous system dysfunction could make your arm go stiff. Limb rigidity is a classic symptom of Parkinson’s disease, for example, and its cause is several steps removed from motor cortex. Even the wrinkling of your fingers when they’re wet involves the nervous system: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2464382/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2464382/
Obviously, issues with your arm could also be caused by problems with your arm, but you can’t trivially rule out the brain either.

- DanBC 8y agoYou cunts need to stop saying that physical symptoms can not be caused by mental illness. It's fucking stupid and it makes you look fucking stupid.

- dang 8y agoCould you please not post dismissive responses even when another comment is over-the-top? Users here need to post civilly and substantively even when someone else isn't. Also, while I have you, could you please stop creating accounts for every comment or two you post? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html. HN is a community.

There are legit uses for throwaways, just not routinely.
