Im sorry after reading your comment I am left with confusion, I am not a doctor so I have a hard time understanding.
My comments here would be similar to a previous post, so please check recent posts near your post.
Hashimoto's patients often if not always have chronic infections that cause the condition. They also usually have other signs and symptoms, and this can lead to incomplete diagnoses for other autoimmune diseases (such as RA, Lupus, etc.).
In addition, they usually have other signs/symptoms that appear to be unrelated to their major complaint ( in your case, tinnitus, but this could also be visual problems, GI problems, etc. among others).
When such complex cases are examined for the presence of chronic intracellular infections, they usually come up positive. Importantly, successful treatment of the chronic infections, which is not easy and takes some time, generally results in reductions in severity of symptoms, and often eventually complete recovery.
