Although rheumatoid arthritis attacks multiple bones and joints throughout the entire body, ninety percent of people who actually develop this condition usually do so in the foot or ankle area. Those who develop this kind of arthritis in the feet usually develop symptoms around the toes and forefeet first, before anywhere else. Rheumatoid arthritis appears to have a genetic component. If it runs in the family, then you will be more likely to develop it as well.

Rheumatoid arthritis is an autoimmune disorder in which the body’s own immune system attacks the lining of the membranes surrounding the joints. This causes inflammation of the membrane lining, and the gradual destruction of the joint’s cartilage and even bone.

Some of the most common symptoms that are associated with RA include pain and swelling of the feet. Stiffness in the feet is also another common symptom that people experience. Those who have RA in the feet usually feel the pain in the ball or sole of their feet. This can get to be very painful at times. A person's joints can even shift and become deformed after a period of time.

In order to properly diagnose RA in the feet it is usually necessary for a doctor or podiatrist to evaluate the area. Your doctor will also question you about your medical history, occupation, etc., to determine whether anything in your lifestyle may have triggered the condition. There are a number of tests that may be performed to help diagnose RA, such as a rheumatoid factor test. There is, however, no one single test that will tell you for sure if you have RA. There are different X-rays that can be taken as well to determine if a person has RA in their feet.

There is a range of treatment options for rheumatoid arthritis. Treatment of RA is usually a lifelong process that includes a variety of methods of treatment and therapy. Your doctor can prescribe special shoes that should help with arch support as well as heel support. A physical therapist can help those with this condition learn exercises which will keep their joints flexible. Surgery may be needed to correct some of the issues with the feet, such as bunions, and hammertoes. Fusion is usually the most successful surgical option for rheumatoid arthritis. However, people need to keep in mind that there are some risks associated with these surgeries.

Athlete’s foot, or tinea pedis, is a skin disease caused by a fungal infection.  The infection typically occurs between the toes, and the feet are most subject to this disease because shoes best create the warm, dark, and moist environment in which fungus thrives.  Other areas that create a similar environment, such as swimming pools, public showers, and locker rooms; can also promote fungi growth. 

Symptoms of athlete’s foot include dry skin, itching, scaling, inflammation, and blistering.  Sometimes, blisters can evolve into the cracks or breaks in the skin.  The exposed tissue can then create pain, swelling, and discharge.  The spread of infection can cause itching and burning as well.

While athlete’s foot commonly occurs between the toes, it may also spread to the toenails or soles of the feet.  Other parts of the body, such as the groin or underarms, can also become infected if they are touched after the original area of infection is scratched.  Aside from physical contact, athlete’s foot can also spread through the contamination of footwear, clothing or bedsheets.

Proper foot hygiene is essential in preventing athlete’s foot.  You can prevent the fungus from spreading by frequently washing your feet using soap and water, thoroughly drying the feet between the toes, changing shoes and socks every day to reduce moisture, and ensuring that bathroom and shower floors are disinfected.  Other tips include using shower shoes, avoiding walking barefoot in public environments, wearing light and airy shoes, and wearing socks that keep the feet dry.

While treatment for athlete’s foot can involve topical or oral antifungal drugs, mild cases of the infection can be treated by dusting foot powder in shoes and socks.  Any treatment used can be supplemented by frequently bathing the feet and drying the toes.  If proper foot hygiene and self-care do not ease your case of athlete’s foot, contact your podiatrist.  He will determine if the underlying cause of your condition is truly a fungus.  If that is the case, a comprehensive treatment plan may be suggested with the inclusion of prescription antifungal medications.

Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet.  Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.

Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.

Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.  

Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.

One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.

Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.

Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.

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.
