Welcome TheRiddler, the first thing you should do is go see your primary care doctor, a blood test can help narrow down the reason for your symptoms. From the blood test on your doctor will narrow down and recommend a neurologist if it is indeed a form of PN.

Just some word of advice, it takes a long time to get an appointment with most neurologists, so it's better to do so as soon as you can. It took me a little over two months to get an appointment with a neurologist. So it's important to start the process of finding out the reason for all your symptoms.

I hope your symptoms aren't related to PN, but if it is, you've come to the right place, the people on this thread are not only a great resource, but a great inspiration to continue to be abstinent from alcohol. I've just surpassed the year mark of being sober and I credit that to everyone on this forum.
