Thank you so much for your kind words UKBloke. Agreed with your words. Tinnitus pushes sufferers to the limit and crushes both your soul and body. I completely understand some people couldn´t cope with this awful condition and commited suicide.
In regard to your question, yes, my brother suffered tinnitus for quite a long time, almost two decades. The level of care he received from them was abhorrent, unprofessional and utterly disappointing. He went to the best ENTs and audiologists of our country but to no avail. The first years he underwent different treatments and approaches, such as taking Trimetazidine, B12 injections, benzodiazepines, Thiethylperazine, etc. as well as he underwent MRIs, audiometry tests, etc. He also tried some hearing aid maskers back then but somehow were ineffective or they didn´t make the adjustments properly.
Fortunately, he improved towards the second year after he stopped taking all those nasty drugs, most of them ototoxic (Thiethylperazine was pulled from market more than 10 years ago and Trimetazidine is no longer prescribed for tinnitus). He still was having bad days but definitely there was an improvement overall.
Over the years, he suffered several setbacks and short spikes but his tinnitus was quite manageable and much less intrusive.
Unfortunately for him, and since 2014/2015, he started to experience awful spikes, different tones and a higher severity of his tinnitus. His last two years were really brutal.
I am going to be honest... I don´t think VAD clinic took the whole thing into account. Even though we tried to retrieve and collect as much information as possible in terms of documents, treatments, medical reports, etc. we didn´t gather a huge amount of documents in total. However, his last medical report proved to be crucial. Up until that moment, no doctor/ENT had stated that my brother was literally "suffering". By reflecting how severe, brutal, intrusive and invasive his tinnitus was, that particular report was explicitly indicating the suffering and the agony he was enduring.
Regards.
