Single ear hearing loss above a B7 or C8, the last octave on a full piano keyboard, will not change your life. Many have similar hearing loss. It is common as one reaches 40 years old to lose hearing in the high ranges. You just lost it a bit earlier. But, if the pred helps it, as I said, it is not totally lost. Resolving the inflammation will help. You may have nerve conduction issues than can heal over time. B-12, folic acid (in a B-50 Complex) and such can help nerves heal.

Please don;t lose hope.
