Hi Kfschall,
Welcome to NeuroTalk Support forums.
I know several people with tinnitus. There doesn't seem to be an effective solution to date. Some have learned to ignore this somehow.
Mark has a lot of knowledge and insight; I am glad he was available to respond to your question(s).
I am glad you are here and are asking questions.

I wish I had thought of coming here to ask questions when I'd first sustained a concussion and was not recovering quickly.
Sounds like your employer needs to "go by the book" on "reasonable accommodations" for handicaps/disabilities/conditions needing extra consideration. This is a plus for you, as it means your employer is willing to make reasonable accommodations if criteria are met.
Many members of this forum are very knowledgeable about concussion, PCS, TBI. I am here learning from them. I am sorry I don't have suggestions for your tinnitus.
Again, welcome!
