This disease involves contraction and relaxation of the muscles. This disease can be reason for more serious disorders. These serious conditions can be multiple sclerosis, spinal injury and amyotrophic lateral sclerosis. Patients who are affected with this disease can be very anxious because the signs and symptoms of benign fasciculation syndrome can change a lot. In the most cases this disease can last with years.

  1. very good post.. Is there any other home remedy for nerve twist.. Other than moving to doctor .. Is it possible to relax nerves initially using home remedy..

    • For quick relief temporarily, cold compress can be used. Also, giving warm compress (cloth dipped in hot water) improves blood circulation and improves healing process. Another method is warm oil massage. These will definitely reduce the pain and improve healing process.
