Normal pain relievers rarely have a major effect for neuropathic pain. Anxiety can be a major problem. Education to allay fears, meeting other people with CIDP to understand what may happen is often good. Fatigue is a common symptom. Treatment for this is to optimise the therapy.
Steroids can cause some weakness.
One looks for other causes of why the patient is not well. It is helpful to encourage the patient to get out and get on with their lives. Some patients will only require one treatment and then return to normal. But most of such patients will relapse but some have long remissions. Why this is so we don't know.
