dun worry. CIN is very common. 我初初都好worry ga cos i dun know what is it. so i ask my friends about this. one of my friend got CIN 1 and one got CIN 2 and i got CIN 3. 一個 did 'leep' at government hospital. another at private hospital. both of them told me its painful. but i am lucky, my doctor's skill is good and its not painful at all.
