Feeling Better: More Exercise/Activity?

Since arriving in Korea, there haven't been many days I've been stuck at home in my apartment. In fact, most days I've been out for at least a few hours, if not longer, rushing around from district to district in the large city of Busan. I've hiked up one mountain, but aside from this there hasn't been much physical exertion, but there has been an awful lot of walking around. This is much more exercise than I got in the UK, especially considering that since developing Meniere's, I've spent a lot of days housebound because I felt too ill to risk going out.

And therein lies another possible Catch-22 situation. Since arriving in Korea, I was determined to go out as much as possible, and not spend my time in the country stuck inside. Did I end up feeling better because I pushed myself, and took the risk of having an attack in public, which I worked so hard to avoid back home? If that's the case it suggests that I shouldn't surrender to the days when I wake up feeling rough, but just go out anyway and take my chances. I suppose that's what I've been doing anyway, but whether it's coincidence or not I just don't know.
