Fall with pain: If any pain related to an precipitating injury getting worse instead of better with time needs investigation. Have xray done and consult your doctor for proper management.

Stress Fracture: You need to be concerned about a heel bone (calcaneal) stress fracture. This needs to be checked out by your physician or podiatrist.

Plantar fascitiis: a tear of the fascia or stress fracture of the heel should all be ruled out.

Possible Fracture: A fall from a height onto your feet and heels is most commonly associated with heel or calcaneus fractures. Even though initially your pain subsided, sometimes fractures can continue to develop due to the simple stress of walking. You should immediately go to the Emergency Room and get X-rays of your feet and stay off of your feet until then.
