I don’t have the answer, but Googling suggests that lots of nerve problems CAN be fixed either with time, or indeed surgery.
What you’ve got here though is an unproven guess at what might be wrong. And you’re pinning your hopes on that being something that can be fixed.
If I guess that the problem is incurable brain damage, will you feel bad? Was I right? No idea, I guessed.
Try to not put yourself through it.
It is inevitable that people will guess and hypothesise about what is wrong and then people will catastrophise and say that there’s no recovery or that it’s very difficult or expensive, or something else.
This isn’t a good use of your time, don’t stress about it. You won’t get any information you can act upon.
Please join in with the effort to get this condition recognised so that people who do have the understanding to diagnose the problem can start to do so.
There is no advantage to stressing yourself out.
