After a few weeks of trying different layouts and avoiding my mouse as much as possible, I found the source of my issue was not my hand but a nerve in my elbow which was being crushed when using chair arm rests. I was also sleeping with my arms folded up on my chest which kept the nerve under tension when I was sleeping, preventing it from fully healing. I now avoid arm rests whenever possible and sleep with my arms to the side. The pain disappearred after about a week and I've been pain free ever since. I've also naturally reduced the amount of typing/mousing I do as I've got older and my career has progressed.
Community organised free 5km runs every Saturday morning. A great way to get some exercise for all abilities. Even if you walk the route - and plenty do - you'll get support from other participants and the marshalls all the way around. You can make it as competitive as you want.
