Clodfobble, try this experiment: stand comfortably, balanced on both feet, with someone nearby to monitor. Now close your eyes and relax. Have your monitor note whether or not you remain still or must make constant adjustments to stay vertical. My brother, who is deaf, had years of inner ear issues before he lost his hearing. Turns out many Deaf folk have bad knees from many years of making those constant adjustments as the brain was informed by visual information given by the eyes, but we never learned of the relationship prior to his experiences - we thought bad knees were a family thing. If it's an inner ear thing with you then finding out now won't help your knees recover, but attending to your inner ears may help prevent further damage. And you can inform the other family members and ease your worries. It's an easy test. Best wishes.
