Hi, I've been experiencing this thing where my hearing spontaneously stops, then I hear a high-pitched, intensified, moderately loud ring, then my hearing fades back in as the ringing tone fades away. I'm not quite sure how to describe it better than that. It occurs in both ears (not both at the same time, though), just randomly at any point in time. This all happens very quickly, within the space of, around 5-10 seconds, then my tinnitus just goes back to its usual stuff (24/7 hissing, faint ringing tones that come and go). It isn't painful and doesn't seem to be causing any other symptoms (or so I think), just scares me that it might mean something bad is on the way...
My story, in case it helps:
"I am currently 19 years old and first got constant/unchanging, hissing tinnitus after flying (Australia to UK) in December of 2017. I remember hearing it not go away the first night we arrived in the UK. Since then, it stayed at that very low, unobtrusive volume, where I could only lightly hear it when I'd try to sleep. In 2018, I had impacted earwax in both ears and got it syringed out by my local GP with no complications at all. The procedure went as smooth as it could possibly go. Earwax became impacted again (in April 2019) and, this time, after getting ear syringing from a different, possibly less experienced GP, my tinnitus amped up to maybe 2.5-3 times the volume (I also got mild-moderate hyperacusis from that syringing). Not sure about the root cause, as I didn't listen to headphones loudly on the planes (and was always very cautious with headphone volume in general as I'm a musician and am careful with my ears). I've had a hearing test with an audiologist and according to that I don't have any hearing loss at all, so I don't know where to go from here."
