Hello. Yesterday I saw a neurologist, he said we have mild torticollis, prescribed massage, orthopedic pillow and glycine 1/4 tablet 3 times a day. I read that glycine is for children from 3 years old, has anyone taken it? The doctor said it relieves muscle spasms, and also due to these spasms and colic, and glycine will help to remove all of this... But it bothers me that it's for 3 years old, tablets act on the nervous system as well... The doctor is very good, they praise her, we will probably not go to anyone else, d/neurologist there is only one in our district.
