hello and welcome to health care magic,
The basic rule is when you have a problem in the ear, nose and throat then you must consult an ENT surgeon! Only he can help you out with this in any case!
Meanwhile you can take an audiometry
testing along with impedance testing and consult an ENT as soon as possible.
You seem to be having a condition called the vascular tinnitus
which is quite common and if properly investigated and treated can be effectively cured
hope this helps
