Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that fluttering feeling in the ear along with continuous sound of bass drum after exposure to sudden loud sound seems to be
TINNITUS and is most probably due to perforation in the eardrum due to sudden
acoustic trauma [sound trauma] and as there has been sudden pressure difference round the eardrum there seems to be perforation..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like Otoscopy, x ray,
Audiometry can help in diagnosis and treatment can be done accordingly..
In case if there is a small perforation you can be advised antibiotics, anti inflammatory painkillers along with antibiotic and decongestant ear drops..
In case of large perforation surgical repair that is known as
Tympanoplasty can be advised..
To reduce Tinnitus you can also be given symptomatic treatment like tricyclic antidepressants Amitryptalline and
Neuromodulation..
Hope this information helps..
Thanks and regards.
