Plantar Fasciitis
If you find yourself stumbling out of bed first thing in the morning because your heel hurts too much to step fully on the floor, you may have Plantar Fasciitis.
Common in runners, people with flat feet and I've personally seen it in men and women who are overweight and suddenly become more active.
It's a pretty easy fix since the culprit is often tight calf muscles, however, there is usually some lower back involvement which we would treat as well.
