Is Tinnitus curable? There a treatment?

So in November,2018 one morning I woke up and I could hear a wind whooshing noise in my right ear. At first I thought maybe its ear wax or worst case maybe an insect has gone in and is making this noise. I let it be for a couple of days but it really started bothering me which is when I decided to see an ENT. The first ENT I consulted said its not curable (which shattered my heart) and it's something I need to deal with for the rest of my life but he did give me a tablet and an ear drop to put. Post which within 3 days my tinnitus had gone down 90% it was much less noticeable so I decided so another ENT just for a second opinion and he said Im hearing this noise due to cold my tube between nose and ear is choked which has caused my ear drum to be displaced. Its summers now and the noise of fan/ac supersedes my T however some days I still hear it when m in a quite meeting room. I wanna know is there a treatment? And also does it become super unbearable with time.
