Good morning sir diwali bomb blast in my lift ear consult doctor.doctor told a small hole in ear.had a bad day on Diwali day where a Sutli bomb (The biggest of all Diwali bombs) exploded just two-three inches away from my ear. I immediately had a hearing impairment, not a complete hearing loss, but a partial loss where I had a sudden burst of ringing sound and echo. I consulted an ENT specialist and he said my eardrum had become punctured due to the impact of the sound and he also found some blood from the drum. He said it could be cured within a month. But, the problem is that I have still that echo problem in my ears and I can’t hear the sounds perfectly. It bothers me a lot. I am even scared it might be with me forever. The doctor has even stopped prescribing antibiotics and said it would be cured without any antibiotics. Please suggest me whether I should approach some other doctor or just continue with his suggestions. Medication:- Rudimin Alday RD
