Hello Doctor. I Am Anne From Malaysia. I Am Fifty

Hello Doctor. I am Anne from Malaysia. I am fifty two years old. A few months back I had this pull in my left leg especially when I drive my car and was told by my doctor that it was a nerve problem. He gave me neurobion to take for a few weeks. Neurobion did help and am not having that pull anymore. Am wondering what does neurobion actually do for me and should I continue taking it as I have finished the supply given.
