Hi Barbara, I am sorry for your pain. Most common conditions that might result in your kind of heel pain are Plantar fasciitis, which is the inflammation of a layer of tissue near heel, Achilles tendonitis which is the inflammation of a large leg muscle s end, Calcaneal spur or Heel spur which is the formation of a small bony protusion on the bone near heel. Common reasons would be excessive running or jumping, improperly fitting shoes. Main treatment would be adequate rest to the heel for few days, application of ice packs at least two times a day near painful area and changing to nice and well fitted shoes. You might also need an X ray of foot to detect Heel spur and if the pain is very severe and not bearable with supportive measures, your doctor might choose giving a local injection containing low potent steroid like triamcinolone which should only be done under the direct supervision of a qualified doctor. Take Care!
