Steroids also deplete potassium, which causes muscle weakness.

No, steroids are not always given for PN.

They are sometimes tried when a person is suspected of
having GBS ... or a rapidly demyelinating process. Some autoimmune processes may respond to steroids. They are used for example in Myasthenia Gravis.

Most sensory PNs are slowly progressive and steroids are not
typically used.

Ok, I will bring all this info to my neurologist. I'm scheduled to meet with a new Doctor at a teaching hospital in january. My sister actually works there and told me she may be able to speed up the process, which would be great.

Thank you again, Mrs.D, your information has been really helpful. I'll continue checking in and posting any new developments. Just in the few days I've been off the aczone, I've noticed some changes, primarily an increase in sensation and feeling less exhausted... hopefully the trend continues.

@kgc:

Have you also taken Accutane?

If your major complaint is muscle weakness? Then you should
also consider myasthenia gravis. This is an autoimmune disease where
antibodies attack the neuromuscular junction.

Often it is difficult to get a diagnosis of this.
Here is our MG forum, where you can ask about it:

High dose steroids are often used to treat this disorder.
You might want to read there and ask some questions.

No, I was never on Accutane.

The Muscle weakness is a fairly new development. Primarily in my forearms, and it's usually one arm at a time. Very odd. I'll check out the link you sent me, thanks!
