My wife suffered similar to you. Eventually the GP referred her to the ENT specialist at the local hospital. She went through various tests etc and the consultant suggested an operation to 'close the hole in the eardrum'.
It took about 12 months of visits, treatments and consultations but eventually she was offered the op. The consultant told her that it would definitely close up the 'hole' and significantly reduce tinnitus, but there was a risk her hearing would be permanently impaired. We talked about this for ages before she decided she could not continue with
the constant infections and the constant 'noises'.

The operation meant an overnight stay (first time in hospital!) and was painful for a week or so ........ but was an 85% success. The perforation closed up 100%. The tinnitus noise easily manageable (some weeks it's nothing) and her hearing not too badly impaired (manageable).
If there is a cold wind she needs to take care as some pain and noise will occur.
If she exposes her ear to loud noise for any length of time she will suffer.
But overall she is pleased.

Why not try to get another consultation at the hospital ?
