I have received a blow to my left ear 1 day ago. I started to hear a ringing sound for some time. After some time, the ringing sound disappeared but from then my left ear is feeling clogged and I am not able to hear properly with my left ear. A little pain is also there in my ear. I feel there is a rupture in my left eardrum because when I press my nose and blow out air, I feel and hear air coming out of the eardrum. Will this lead to permanent hearing loss? Will it heal automatically and should I consult a doctor? What precautions should I take so that middle ear infections do not take place?
