Hello, Kebsa.

Have you ever had a sleep study to rule out a sleep disorder for your fatigue? If not please discuss it with your doctor. Also there are meds that can help some patients with fatigue.

Sensory symptoms are difficult and sometimes impossible to treat.

Unfortunately, steroids might only be a temporary solution to a life long symptom. Another option might be physical therapy or Occupational therapy.

You can also change to a different Disease Modifying Drug (DMD). Your options - Avonex, Rebif, Betaseron, Copaxone and Tysabri. Some MS patients find they do better on one drug over another.
