Thank you for your query.
1. The most common cause for this is Eustachian Tube Dysfunction
. The noise may be Tinnitus
2. The Eustachian tube connects the nose to the middle ear and blockage or altered functioning of this tube may cause the above symptoms.
3. The first step will be to locate the cause of the ear drum scarring (Tympanosclerosis
). Get your Pure Tone Audiograms (PTA)and Tympanogram (Impedance Audiogram or I/A) done.
4. You may follow up with the results of the investigations for further treatment options. In the meantime, try an OTC anti-allergic decongestants and regular steam inhalation through the nose and mouth.
