Yup. Permanent. I developed it. Maybe if you catch it early and stop drinking they can do something about it provided you don’t have diabetes or some other nerve-type issue. I have a mild form of it primarily in my toes. I’m 71 and have been sober for 9 years. It’s a little scary to live with as you get older and start feeling that your whole body is slowly falling apart, but at least I’ve gotten used to it. A lot of people have it.
Do talk with a doctor.
