The best advise is to seek outside counsel that works on a contingency basis...........have him make an appointment outside the VA system and hopefully demonstrate that you have a bilateral condition. A 0% rating is the 1st step, even a 0% grants to you the evidence of a service connection and its a proven fact that a hearing loss caused by nerve damage to the point that tinnitus is evidenced that condition will never heal itself.......it can only become worse as you age. How does the VA doctor know that your right ear is not a result of service connection when the left ear offers evidence of a service connection? He/She does not.....its just an opinion that can be legally challenged.
