Welcome to Just Answer:
Yes, it is likely that your other symptoms of fatigue and loss of appetite are part of the same underlying cause as the tinnitus. All these symptoms are likely complication from the viral encephalitis causing residual nerve sensitivity changes with resulting tinnitus, and post viral syndrome with fatigue and poor appetite due to reduced body energy molecule generation with persistent body free radical or immune system changes. I suggest that your doctor include a consideration for the post viral complication of chronic fatigue syndrome and/or fibromyalgia. I would suggest that you consider closer evaluation with your doctor for immune system changes and possible deficiencies in certain important body components including levels of ESR, C-reactive protein, Anti-nuclear antibody
function tests, liver function tests, complete metabolic panel, complete blood count with differentials, serum iron, RBC folate, and vitamin B12 levels. In the meantime, I suggest that you use over the counter B-complex vitamins and antioxidants such as those containing glutathione in the reduced form.
