wet cough dry cough

i had constant headaches since months back.
and i think it was a migraine.
sometimes it was so major and lasted for days.
so bad that painkillers seemed to do nothing.
after a few months, it came with a package - sore throat, cough, flu, you name it.
but now i got a lot better.
no more sore throat and massive headaches at night.

but.. the cough is still there.
it used to be a wet cough but this time it has turned to be a dry one.
everytime i breath in, i feel like there's something irritates my throat and makes me cough.
i'm actually okay with it until my bibik said "macammana ni nanti pengantin dok batuk2 je".

okay, so now i think i really need to do something.

any advice?
