Do not use cotton buds to clean your ears.
They tell you "it's dangerous, you'll damage your ear drum".
That's true, if you are an imbecile! You don't need to have much sense to avoid doing that.
They should tell you "it doesn't help, it just makes things worse!".
According to the doctor I saw today, it just pushes the wax further in. You should not put anything, even you finger, into your ear. Wax is fine, it grows out and will only block your ears if you ram it deeper into your ear by poking some object in.
Now I know the second part, I will not use cotton buds in my ears again, and I hope you won't either
