Last month one of my tinnitus symptoms was spiked pretty bad so to sleep I had I used ear buds earphones for masking as the normal masking was not working well, I kept them all night but I was sure to put it at a low volume.
Unfortunately this seems to have made my tinnitus considerably worse for the past few weeks now I have a gotten a new tone which is pretty loud and it definitely was not like that before.
I did not think I was doing anything wrong since some sounds therapies require you to wear noise generators all the time.
I am just guessing, but I believe the problem may've been too much sound exposure. Even though you had the volume low, they were in your ears all night. It's much better for your ears if you have some type of background sound--but not playing directly into your ears. I do know that sound therapies will require you to wear sound generators, but I don't believe you wear them all day. Neuromonics, for example, only requires you to wear earbuds for several hours a day.
Another explanation could be your own individual sensitivity. Perhaps, wearing earbuds all night on a low volume is fine for some people, but it was not fine for you. Just as everyone's tinnitus is unique so too are individual's sensitivities and tolerance for sound. But I could be be totally wrong. This is just my guess from researching various things about tinnitus and noise exposure.
If I were you, I wouldn't wear earbuds any more--at least not for several months. Give your ears a break. Keep background sounds on, but use a machine or something. I'd also take look at the NAC thread. You might try some antioxidants for a while. They won't hurt you, and perhaps they will help repair any damage you might've done.
The good news is you're probably only experiencing a temporary spike. I'm sure you'll go back to normal, but it might take a few months.
Here's the link to the NAC thread:

If you decide to take NAC, please also consider other drugs you are taking and look for possible interactions. WebMD is usually a good source for this type of information. For the link to NAC, click
