This is called pulsatile tinnitus. I have it too. It drives me nuts!

Yes it was very strange, mine only happened when I turned my head to the left.

Yes, I frequently have that happen. It’s a very strange sensation hearing your heart beat. It scared me when it first started years ago and I thought there was something wrong with my hearing. Now that I know I have PH and others have this symptom, I feel a lot better.

Thanks ChristineS for the link to read more. It helped me a lot. I also have hyperthyroidism which could also play a part in what I’m experiencing. My grandmother use to say, “If it’s not one thing, it’s another”. I will stay strong in my faith and continue to rely on the great doctors I have. ❤️
