ENT / Neuro opinion
Detailed Answer:
Hi.
Gone through the Medical history and query.
It looks that a 20 year old incidence may not have anything to do with the present problem.
Your present problem of Tinnitus- sound like washing machine and sense of falling is there for a week.
Blood and CT scan are normal.
You are already put on Labetolol for a
high blood pressure. Still suffering from High BP and Tinnitus.
I would like to give you some explanation to understand the mechanism and causes of tinnitus- The
inner ear has 2 apparatuses, one for hearing and the other for balancing.
The one for hearing has a arrangement like Shankh (conch shell) and has many hair cells,. Each hair cell moves with particular sound and the brain keeps the register of each and every sound. This is how we can recognize any sound even after years. Now in your case the hair cells allocated for washing machine sounds are moving on their own so the brain is having a perception of this particular sound you are hearing. ( I hope you do not mind for this lengthy answer).
Now it is practically not possible to pin-point the cause of this and hence the treatment is always on an empirical basis.
The probable reasons can be :
As you noticed - the high blood pressure causing a damage to the blood vessels supplying this particular part of hearing apparatus and the apparatus for balancing (Cochlea). For this the Doctor has already prescribed you medicines. IF this medicine is not helping to lower the blood pressure , your Doctor may change to another one.
Another ''possible'' reasons can be infection by a virus / reduced blood supply to this part in spite of high blood pressure may be due to
vertebral artery blockage/ Tumor in nearby area ( rules out by CAT scan already) and so forth.
I would recommend for such a patient to go for an ENT check-up, consultation with a
Neurologist, Color Doppler studies of the neck arteries / MRI
Angiography.
As I said, the treatment is on empirical basis and of the cause if could be found out.
Stugeron (
cinnarizine ) taken in a thrice daily doses helps occasionally.
IF the problem persists for a longer time in spite of the treatment one may try acupressure/ puncture an alternative therapy in addition to the one prescribed by your treating Doctor.
So wait and watch with continuation of the treatment is a better policy.
