Maybe. I know post-surgery on my sinuses last year, I'd get ringing only if I laid back in a specific posture but it'd go away within like a minute of getting up. That posture (laying back against my wall propped up by pillows) does not induce that ringing anymore... it's strange. All I know is that THC never caused any spikes during the 2.5 months after the surgery. Hell it wasn't even causing them the weeks before where I gradually started using again after a 6 month tolerance break. And last night, my ears started ringing LESS after I got high, so I don't get it. Like most of the time it gets worse, sometimes it doesn't change, sometimes it even might get better. Potent flower or dabs will spike them the worst, but then, I've had times where they didn't. So I wonder what THC could have to do with what's going on, even the acupuncturist was like hmm, that doesn't sound like it would've caused this.
Obviously I have no idea

The effect of delta-9-tetrahydrocannabinol (THC) on cerebrospinal fluid (CSF) flow in rats was studied. When administered in doses of 25 mg/kg to 45 mg/kg intraperitoneally, THC caused inhibition of CSF flow; in larger doses a smaller response was noted. In response to THC, CSF flow showed an initial drop, a return toward baseline, and a secondary decrease. It is postulated that this biphasic effect is due to a combination of THC's sympathomimetic effects on the CNS plus the local action that this drug has on choroidal synaptosomal neurotransmitters.

The effect of delta-9-tetrahydrocannabinol (THC) on cerebrospinal fluid (CSF) flow in rats was studied. The ventricular system of rats anesthetized with ketamine sulfate was cannulated via cisternal puncture, and CSF production was recorded. When administered in doses of 25 mg/kg to 45 mg/kg...
