well.
You might not have gotten lyme. You might have gotten it, and your body fucking killed it like it's supposed to (tinfoil insanity about island-based CIA run bioweapons programs aside, descriptions of Lyme exist in documents from the 1700s, so it's been around a while).
In any case -- the relative I know who had it -- got bitten by like 20 ticks, thought nothing of it except "gross", and then over the 6-12 months later their health spiraled, they were having insane joint pain and neuropathy that required massive opioids and still left them bedridden, and it took long term antibiotics to actually deal with it. When people get it bad, it's really bad, and I don't think you would just have zero symptoms and then develop lyme-based tinnitus after an acoustic trauma.
So, probably just stop thinking about it; if really curious, you could try the Cowden protocol or something and see what it does.
