Wake up frim sleep due to change in volume and pitch?

Hi! I have T for about 12 days now. I was taking antibiotic for sinusitis and stopped it yesterday afternoon. But last night I woke up because the ringing has become louder than usual. It stayed like that for a few minutes then died down and I was able to sleep. Then after an hour I woke up again because it has gotten louder (but not louder than the first time I woke up) and the pitch was higher. Then it died down again. I slept and woke up to my alarm. Now my T is quieter.

My appointment with my ENT is tomorrow.

In the meantime, I would love to know if anyone experienced this before? I have sinusitis and history of TMJ (not sure if I have it now as I cannot diagnose myself).

I also have T on left ear and muscular discomfort on back of neck and upper shoulders but this may only be due to interrupted sleep due to T.

Help?
