What Causes Pain In The Left Side Of The Head After A Cervical Spine Surgery?
Not always a bad sign
I partly agree with your specialist doctor if he had done the complete evaluation. However a Neurologist should also rule out any serious reasons for these new symptoms of high pitch ringing in the ear.
This numbness and ringing in the ear may not be serious sign all the time. You should not worry about it instead try to find the right reason for numbness.
Studies after acoustic neuroma surgery
There are good studies which said that the ringing sound in the head appeared after acoustic neuroma surgery. This is particularly high in young people less than 50 yrs who had this surgery. In such cases the reason for this kind of sound was referred to something in the brain stem or post-brainstem pathways.
This sound was not existent before the surgery but appeared in few after surgery.
The treatment options exist now but you should talk concurrently to Neurologist, Audiologist, Neurosurgeon and ENT.
