I'm just back home from an event where there was a lot of children. I carry musicians earplugs (the plastic ones with two cups and a stem through them).
As I was going out of one room and into another I knew all theses kids were present and it was loud because of their chatting so I popped these in. Once I was away from the danger zone I went to take one of them out and it must have created a vacuum in my ear canal as I felt it pop and then my ear made a horrid loud ping noise, almost like the eardrum had been rattled. The bottom smallest cup was inverted, like a umbrella that's been sucked in.
The noise itself went away quickly and at this stage I can't tell if my tinnitus has spiked or there's any new noises as I hear a small variety throughout the day/night that come and go?
The warning is if you use these kind of plugs to make sure you get some air in first and could I have caused any damage? If it spikes when's the latest I'll know by?
I've taken a dose of magnesium citrate and B12, is there anything else I should do?
When you push in or take out earplugs that create a seal, you cause an increase in pressure (or suction/decrease in pressure, respectively) on the eardrum/ossicles attached to the eardrum (which make up your "middle ear"). Basically this action causes very mild barotrauma. For most people this doesn't matter, they can insert/remove sealing earplugs or headphones hundreds or thousands of times and never notice anything. But for some people, like me, and maybe you, this creates a tinnitus which doesn't resolve until the underlying mechanical (of the eardrum or ossicles, or maybe even something of the inner ear, who knows!!) change heals. The tone (for me, 1220hz/1275hz/1340hz/1420hz, that sometimes alternate in a morse-code like fashion) used to last a few minutes for me, but with every subsequent pressure/suction (especially if it occurred before the previous one had fully healed), the duration increases. Currently I'm at about a month for a full heal!
If you have any questions, let me know. If you are experiencing fundamentally the same thing as I am, I'd love to help in any way I can, and I'd love to have any more information of your situation you can provide. I'm continuously trying to build my understanding of this thing/come up with testable theories of how it works/what worsens it/what improves it, so I can live with it better.
The one thing I am quite sure about is it's an objective and/or somatic tinnitus produced by the mechanic damage to... whichever. My tinnitus tones for this particular issue, unlike some other tinnitus I have, interact harmonically (not sure thats the right word) with closely matched tones — I can make it wobble or sometimes negate it entirely if I get the frequency/phase just right.
