A. it is usually considered as normal for this age,you should not worry for now,if it is no+tjt associated with any other problems repetitively.usually it may not require any kind of treatment or medicine . if you have any more doubts,keep observing, wait and watch and u can also get clinical examination done once by the doctor available nearby and get further guidance regarding this.
