Then we check trigger points of gastrocnemius muscle and inject lidocaine 1 \~ 2 ml each up to four points. One week later (T1) we record numeric rating scale (NRS), the frequency of cramps and insomnia severity index again, check trigger points, and if any, inject lidocaine. If the patient do not come, we get numeric rating scale (NRS), the frequency of cramps and insomnia severity index over the telephone.
