hello and welcome to HCM,
You are suffering from tinnitus and since the sound gets reduced when you press below the ear it is an vascular tinnitus
. But since your vascular surgeon has mentioned the arteries are fine then let us go over a few points:
1. Get a full ENT examination including the state of the drum and get an audiometry
testing done to assess the hearing
2. Get a CT of the temporal bone
to rule out any other common cause of tinnitus
3. Get a full blood profiling including cholesterol
level estimation to rule out atherosclerosis
of the blood vessels.
4. Since you have mentioned that the vascular surgeon said that the arteries are fine then I am assuming that you have done an angiographic study of your carotids. If not I would definitely advice you to do the same.
5. If all the tests are normal then you have diagnosis of essential tinnitus. If thats the case then there is a new drug called the TINNICAR which is a prostaglandin
analogue and is available in both tablet and injectable forms. I have been having a fair degree of success in relief of tinnitus by using this drug. Ask your ENT about the same
6. Learn some relaxation technique like the yoga which can reduce the stress you are having because of the sound and may even reduce the sound
7. If you have hearing loss
then hearing aids can help you in hearing and as well as reduce the sound
8. While sleeping when the sound is the most then concentrate on other sound like the fan, radio or a big clock
take care and do not concentrate on the sound much, i know its easier said than done but its in your hands completely.
