Four years after my last entry: I still can't run, but somehow I'm back to climbing (and doing the approaches/descents!). My heels still hurt sometimes, but it's tolerable and I just keep going. What was the cure? Vitamin D. I was deficient and as soon as I started taking supplements, my whole body started feeling better. It only took 6 years to figure that out! Ugh. Anyway, I should live a fair bit longer now that I'm able to exercise again. Wheee
