The reason for my tinnitus was because I had C-Diff from a surgical complication.

I was put on 4 antibiotics to save my life. I was in a coma from the SUPER INFECTION and they needed to give me the antibiotics to get rid of the massive infections. My temperature went up to 106 degree F. The infection and antibiotics gave me the bilateral tinnitus. Since then I hear them ever since then (1994).
They sound like a high tone whine. I tested for the noises on my piano and they are two tones...[two octives above middle C - E flat]. I hear them day and night and they bother me any time of the day or night.
I have utilized Sound machines of various types to filter out the noise. I have used biofeedback to think about other things beside what is constantly going on in my head. I use my radio or my TV in the background to always have some noise/talking going on so that outperforms what is going one in my brain. This way I can concentrate on what I want to do instead of hearing the annoying sound in my head.
Better yet, I have great hearing aids that have a program that I ALWAYS put on that has a blocking or white noise on it which almost matches my tinnitus. I like listening to it because it is more pleasant to listen to then what is in my head. My audiologist can turn it up more or I can even turn it up on my iPhone (where my Resound hearing aid is located) if I want it louder if I must without causing any migraine or hypercusis.
Stability and moderation is what I need because too much stimulation of my brain will cause overload and exhaustion.

Answer to your question of tinnitus and hearing loss should be directed to an audiologist right away. Write down your thoughts and questions about what you are feeling, when this happens and what you would like to do about it. Find an audiologist that will be able to answer your questions and also be able to direct you to what you can do to help you with your hearing loss/tinnitus.
