Heel Pain
Most commonly, heel pain is caused by inflammation of the plantar fascia — the tissue along the bottom of your foot that connects your heel bone to your toes. The condition is called plantar fasciitis.
Plantar fasciitis causes stabbing or burning pain that’s usually worse in the morning because the fact that the fascia tightens overnight. Once your foot limbers up, the pain of plantar fasciitis normally decreases, but it may return after long periods of standing, increased activities or after getting up from a seated position.
Plantar fasciitis usually develops gradually, but it can come on suddenly and be severe. And although it can affect both feet, it more often occurs in only one foot at a time. Be alert to; sharp pain in the inside part of the bottom of your heel, which may feel like a knife sticking in the bottom of your foot. Heel pain that tends to be worse with the first few steps after awakening, when climbing stairs or when standing on tiptoe. Heel pain after long periods of standing or after getting up from a seated position. Heel pain after, but not usually during, exercise Mild swelling in your heel
Under normal circumstances, your plantar fascia acts like a shock-absorbing bowstring, supporting the arch in your foot. But, if tension on that bowstring becomes too great, it can create small tears in the fascia. Repetitive stretching and tearing can cause the fascia to become irritated or inflamed. The causes of plantar fasciitis can be:
Physical activity overload
Plantar fasciitis is common in long-distance runners. Jogging, walking or stair climbing also can place too much stress on your heel bone and the soft tissue attached to it, especially as part of an aggressive new training regimen. Even household exertion, such as moving furniture or large appliances, can trigger the pain.
Arthritis
Some types of arthritis can cause inflammation in the tendons in the bottom of your foot, which may lead to plantar fasciitis.
Faulty foot mechanics
Being flat-footed, having a high arch or even having an abnormal pattern of walking can adversely affect the way weight is distributed when you’re on your feet, putting added stress on the plantar fascia.
Improper shoes
Shoes that are thin-soled, loose, or lack arch support or the ability to absorb shock don’t protect your feet. If you regularly wear shoes with high heels, your Achilles tendon — which is attached to your heel — can contract and shorten, causing strain on the tissue around your heel.
