How to identify which frequencies cause hyperacusis discomfort

Hi,

I currently have the ability to adjust my own oticon own 2 IIC settings with genie 2 and expresslink 3. I suffer from severe discomfort with some high frequencies in the right ear which can be painful and from self diagnosis seems to be hyperacusis although I have never suffered from tinitus. Its like a speaker on a PA system is peaking and I would like to understand the best way to identify which frequency causes the issue. I can turn the all frequencies down and it will get to a point where it has been eradicated but i have lost a large amount of hearing aid gain by this point and I would only improve my hearing in the right ear marginally.

Heres my hearing results.

and heres my current oticon OWN 2 IIc settings after in-situ testing and feedback analysis.

Thanks.
