Where exactly? Here's a pretty accurate description of the discomfort, the "heel bone arrow" is spot on for me:
None of it bothers me during an activity, it's the shut down that gets me. The pain goes away after 1 or 2 rounds of icing and it does not linger to the next morning. Just that it flairs up after each time I play.
As for changes in routine, not much. All of the discomfort came about after I took a mis-step and landed squarely on that heel. I was wearing shoes and all, but it still hurt like a mother at the time.
