Hi, i had something like a cyst inside my nose full of puss, which was hard and painful. It had made my left side of the nose swollen, crooked and it hurt to touch. i could nt breath, and the puss that came out had a very foul smell. It did not drain properly, instead i still have a small hard cyst at the same spot, and it causes extremely foul smell from my left nostril. Plz enlighten me what to do, and if there is something serious.
