Welcome to the forum. Have you found any reason for the recent spike, such as drug side effect, stress/anxiety, loud sound exposure, ear infection or ETD, or whatever? Anyway, good luck to your visit to the ENT and hope it is something fixable. If you are bothered by the current T level of ringing, perhaps consider masking it so you won't stress out with it. If you haven't masked yet, here are some suggestions. God bless your recovery.
1) Mask at bed time so you can sleep better. Find whatever sounds/music that are soothing to you. You can use a sound machine or sound pillow for this, or a computer with speakers.
2) If you need masking on the go, try load an ipad with nature sounds or music using itune, or use smart phone. You can also order some nature sounds via 'itune' to play on your PC.
3) If you have computer and speakers, you can try these excellent masking sounds:
TT's audio player:

or this online sound library, particularly the self-mix nature sounds:

or download free sound generator 'aire freshener':

or search youtube with words like 'tinnitus masking sounds', 'white noise', 'rain sound' etc.
