The reason I asked is because a nurse I worked was told she had polyneuropathy, but when she went for a second opinion from a neurologist, it was dismissed and she was told she had fibromyalgia.
In any event, treatment for polyneuropathu includes corticosteroids such as prednisone, which may be prescribed alone or in combination with immunosuppressant drugs. Plasmapheresis (plasma exchange) and intravenous immunoglobulin (IVIg) therapy are effective. IVIg may be used even as a first-line therapy. Physiotherapy may improve muscle strength, function and mobility, and minimize the shrinkage of muscles and tendons and distortions of the joints.
The course of polyneuropathy varies widely among individuals. Some may have a bout followed by spontaneous recovery, while others may have many bouts with partial recovery in between relapses. The disease is a treatable cause of acquired neuropathy and initiation of early treatment to prevent loss of nerve axons is recommended. However, some individuals are left with some residual numbness or weakness.
