Of the 7 years of having tinnitus, this has never happened and this has been going on for almost two weeks now. I'm trying my best to deal with this, but I'm frustrated as I had habituated but with this random mess, how am I supposed to deal with this? I was hoping it was a spike due to the weather changing or being sick, but I'm starting to doubt this.
Has anyone ever experienced this before?
Yes, this has happened to me after a long habituation period and explained it in my post: My Experience with Tinnitus, it is on my Started Threads.
Tinnitus can change for many reasons. Even though you have lived comfortably with it for the past 7 years this can still happen. Did you find out the original cause of the tinnitus because something usually brings it on, and this can be an indication for the change now? I do not want to speculate too much for as I've mentioned many things can be responsible for its onset. Therefore, I will mentioned the usual cause which might give you an indication and something to think about.
If the original cause of the tinnitus wasn't due to an underlying medical problem within your auditory system and this includes hearing loss, then the likely cause would be noise induced. If you were a regular user of headphones, earbuds or headsets, frequently went to venues such as nightclubs or concerts where loud music is played, this would be the reason for the onset of tinnitus. If this is the case which I don't know at present, it's not unusual for a person to habituate as you have in time, and the brain has comfortably pushed it into the background where it is of no more importance. A person might hear it periodically in quiet surroundings or a night, but for the most part they are quite content and there's no need to be concerned about the tinnitus.
All this sounds good. A person may resume using headphones, earbuds or headsets, frequently attend venues where loud music is being played - turn up the volume listening to loud music is car and they are quite happy and content for they have forgotten about the tinnitus. However, it is always there quietly in the background waiting to strike.
If noise induced tinnitus was the original cause of your tinnitus onset, the usual reason for it increasing is because of Sound. Either you have been using headphones, earbuds, headsets too often and probably too loud without realizing it. Or, you may have been listening to other types of loud music through speakers at home or in the car. These are just examples. As I say: if your tinnitus was originally noise induced then in most cases (not all) the reason for it increasing is renewed exposure to loud sounds or headphones/earbud/headset use.
If the tinnitus doesn't settle down it's a good idea to make an appointment at ENT for tests. You might find my article: Tinnitus, A Personal View, helpful and is on my Started Threads.
All the best
