If it is too much and hard creating hearing problems then it will be better to clean. There are some medicines available in the pharmacies which you can use to melt the wax and clean it with cotton (not cotton buds) when it comes out of the ear. Normally the wax will get dropped when it gets dry but sometimes in some individuals it will stay soft/hard and will clog the ear drum creating hearing trouble, itching and uneasiness. It is not necessary to do the cleaning paying 190 riyals but you may seek the help of a private doctor who will most probably suggest you to use the ear drops to melt it. If it is very hard then he/she will do the cleaning.
