Countering this anecdata with my own: I have several rare diseases and I'm quite disabled. I didn't get noticeable effects from my first two Pfizer doses (at least nothing I could distinguish from my chronic illness), while the third gave me flu-like symptoms for 2-3 days. I was happy about this because it told me it was working, and I returned to my (crappy) baseline afterwards with no lingering effects. I wonder if you just happened to get ear ringing coincidentally around the time you got your second dose, and connected the dots even though it might not be causally related.
