The presence of headache, ear ache, fullness in ears & other symptoms may be associated with the prolonged use of headphones, as your profession demands.
These symptoms if not taken care of in the initial stages can lead to hearing impairment
by causing permanent damage to the hair cells in the inner ear
Investigations like Audiometry
, Speech Interference tests, Tympanometry
will be helpful in detecting the extent of damage.
Depending upon which, proper management steps could be taken.
So...it will be better to consult an ENT specialist
to the earliest & discuss about the preventive as well as management strategies.
Wishing you a good health.
Thanks & take care.
