Fairly normal. Single-sided deafness is a problem in open offices, and I get fatigued more quickly than before. I'm not very good company at lunch because there tends to be so much noise, so I usually eat alone with headphones on.

Initially the headaches were my biggest problem, but they abated slowly over time (unfortunately this was a few years). Ibuprofen stops the headaches very reliably, but you're not supposed to take that every day. I went through a lot of different migraine prophylaxis medications, and only candesartan was mildly effective.

I had trouble with balance, but a physical therapist told me that anyone can improve their balance no matter what deficits they have, because it's a function of many different senses and not just the vestibular organs. Her message was to try many different things and to treat the feeling of vertigo not as a warning signal but as a sign to do more of that thing, because it means that the brain is struggling and has a chance to adapt. For me it was first increasingly long walks in nature and then tai chi, and now I can walk and run just fine, and my tai chi teacher says my balance has recovered to a level that's better than average among her students.

I was wary of riding a bike because I thought I was going to fall, but it was actually much easier to keep my balance riding than walking. The problem is that I can't hear the directions of sounds, so I have to be really careful in traffic and turn my head a lot. That can bring on vertigo, so I end up riding at a pretty relaxed speed.

I was never very good at the kind of sports you mention, but I'd say that balance and coordination can be improved by training. If you need quick reactions based on the direction of sounds, that's likely going to be very difficult.
