A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.

Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.

A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.

Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.

For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.

Poor blood circulation in the feet and legs is often caused by peripheral artery disease (PAD), which is usually the result of a build up of plaque in the arteries. Plaque build up, or atherosclerosis, can be the result of excess calcium and cholesterol in the bloodstream, which restricts how much blood can flow through arteries. Reduced blood flow to a certain area of the body severely limits the amount of oxygen and nutrients that part of the body receives, causing degeneration in the muscles and other tissues. Sometimes, poor blood circulation in the feet and legs can be caused by other conditions, such as damage to or inflammation of blood vessels, known as vasculitis.

The lack of oxygen and nutrients caused by poor blood circulation can restrict muscle growth and development, as well as cause muscle pain and cramps, weakness, and stiffness. Other common symptoms include numbness in the legs and feet, skin discoloration in the affected limbs, slower nail and hair growth, and erectile dysfunction in men. In more severe cases of PAD, pain can be present even when a person isn't exercising, and may range from mildly uncomfortable to completely debilitating.

Poor blood circulation in the feet and legs is more common in those who are overweight or obese, have diabetes, high blood pressure, high cholesterol, who smoke, or who have a family history of PAD or related conditions (heart attack, stroke, etc.). Diabetes and smoking place a person at greatest risk for developing poor blood circulation, although advanced age (over 50) can also increase risk.

If you are experiencing poor blood circulation in the feet and legs caused by PAD, it is important to make changes to your lifestyle in order to reduce your risk of experiencing a heart attack or stroke caused by this condition. If you smoke, quit completely -- this will increase the amount of oxygen in your bloodstream. Exercising and reducing the saturated fats in your diet (which come from fatty meats, fried foods, whole milk, etc.) can make a difference in improving blood circulation in feet. It is also important to avoid developing influenza and to carefully control your blood sugar if you have diabetes.

Your doctor may recommend combining lifestyle changes with a prescription medication regimen to improve blood circulation. The most commonly-used medications for PAD are called statins and work by blocking the amount of enzymes in your body that produce cholesterol. They are known by the brand names Zocor, Lipitor, Crestor, and others.

Sesamoiditis is a condition that affects the joint that is just behind the big toe in the area known as the ball of the foot. It is most common in younger people and people who have just begun an exercise program. Since the sesamoid bones are like a pulley controlling the big toe, they can rub against each other and cause a gradual onset of pain. Pain may also be caused by the inflammation of tendons surrounding the bones. If ignored, sesamoiditis can lead to other, more serious problems such as severe irritation and fractures of the bones.

The cause of sesamoiditis is sudden increase in activity. The ball of your foot acts as a springboard to help you lift off when you are jogging or running. Sudden increase in the use of these bones or the tendon that controls them can cause irritation. The tendon then begins to develop inflammation and the joint begins to swell. People with smaller, bonier feet or those with a high arch are typically more susceptible to this condition.

Sesamoiditis is fairly simple to diagnose since the symptoms have a gradual onset rather than a sudden impact. The symptoms begin with slight irritation around the joint shortly after the increase in activity. The discomfort eventually turns to pain with light swelling and possibly redness. Although redness or bruising are rare, this may be a symptom. After each session of exercising, the aggravated joint becomes more irritated and increases into a very intense throbbing.

Treatment for sesamoiditis can vary depending on the severity of the situation. However, treatment is almost always approached in a noninvasive way. For a case that is just beginning the doctor may recommend a very strict rest period that will limit the activity allowed on the joint. If you must be active, a recommendation for as modified shoe or insole, along with bandaging and immobilizing the big toe will be made to ensure that pressure is not placed on the joint. For severe cases, it is typically recommended that the joint and the big toe be completely immobilized to allow adequate time to heal. Ice and an over the counter anti-inflammatory may can help with the pain and discomfort while you are at rest.

When you return to your regular exercise activities, it is recommended that you use an insole that will allow even distribution of impact to your entire foot, rather than just the balls of your foot. This will prevent further aggravation of the injury.

The branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.

To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.

When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.

Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.

Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.

Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.
