Thank you, that's good to know. I always thought it was normal and people other than me just got used to the pulse noise.
If you or anyone reading this any possibility of cardiac issues (high blood pressure, clogged arteries), it would be worth mentioning at your next checkup.
Mine was pretty clearly linked to an injury that eventually caused other tinnitus so I assumed the causes were similar. Note that per the link below pulsatile tinnitus can be quite benign, but is does have some causes worth excluding.
And why is that, since the causes are so varied and often specific?
