Listen to APF and your doctor mate - we were right, you were wrong. lmao
Not laughing really, I've noticed previously that you have some health-related anxiety going on and that can be really hard work.
In future, have a look at realising that your thoughts are just that, thoughts. We think all kinds of shite all the time, all of us. Let them go and then wait until you know the facts, then attend to matters. That will help save you from getting flooded (for no reason other than anxiety) with cortisol, adrenaline etc - both of which feel unpleasant and can lead to other health issues themselves. And also from the anxiety spoiling your present moment, which, given that's all we ever truly have, is most definitely not what we want
And yeah - you can definitely get headaches from blocked ears. Source - me. Decades of feeling that from blocked ears, which is why I was reasonably certain about your condition.
