most helpful answer then you may need to see a different ent for a second opinion. this is an extremely difficult issue to evaluate and it is is unlikely that something as simple as wax impaction in your ear canal or even your blood pressure would be the underlying culprit. some ents specialize in inner ear disorders (a likely area of problem). see if you can find an ent that can do a higher-level diagnostic evaluation. the "rumbling" may be a variation of tinnitus (usually heard as ringing). accompanied by your hearing loss there could be dozens of considerations as to the cause. and. finding the cause if that is possible is only part of the battle. your ent will then need to help you in finding some help in dealing with these annoying symptoms.
