Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.

Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.

At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.

Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates.  They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.

Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.

During your lifetime, you will probably walk about 75,000 miles, which is quite a lot of stress to put on your feet. As you get older, the 26 bones and 30 joints in each of your feet will lose flexibility and elasticity. Your foot’s natural shock absorbers will wear down as well. Having arthritis added to this mix only makes matters worse. Your joints will become distorted and inflamed, which is why arthritic foot care needs to be something to think about every day.

When dealing with arthritis, having additional foot complications, such as bunions, hammertoes, or neuroma, can be a serious detriment. To avoid these, buy well-fitting shoes with a lower heel and good support. Arthritis causes you to lose your arch, so having shoes with good arch support is also highly recommended.

Aside from getting good arch support, the shoes need to fit comfortably and properly as well. A good place to start is by leaving a finger width between the back of the shoe and your foot to gauge proper size. It is also helpful to have a square or rounded toe box in the front to provide even more comfort. Another thing to look for is a rubber sole that can provide a cushion and absorb shock as you walk. This adds flexibility to the ball of your foot when you push off your heel to walk.

Exercise is another key aspect of arthritic foot care. Exercise not only strengthens and stretches your muscles and joints, but helps to prevent further injury and pain as well. Stretching the Achilles tendon, the tendon located in the back of your heel, will give you added mobility and reduce pain due to stress. Another thing you can do is massage your feet, kneading the ball of your foot as well as your toes from top to bottom.

Stretching the Achilles tendon is a simple exercise that you can do at home anytime. Lean against the wall with your palms flat against the surface while placing one foot forward, towards the wall, and one foot behind you. Bend your forward knee towards the wall while keeping your back knee locked straight, and make sure both your heels are completely touching the ground at all times. This will stretch your Achilles tendon and calf muscles as well. You will feel the stretch almost immediately. You can also stretch your toes in a couple ways. One involves taking a rubber band and wrapping it around both your big toes while your heels remain together. Then, pull them apart to stretch your big toe. You can also place a rubber band around all the toes of one of your feet. Then, try to separate each individual toe, stretching them all.

A final step you can take to help your arthritis is taking non-steroid, non-inflammatory drugs or topical medicines with capsaicin. Unfortunately, there is no complete way to remove all of your arthritic pain. However, following some of this advice can go a long way in staying as pain-free as possible.

Gout, typically found in diabetic patients, is an unusually painful form of arthritis caused by elevated levels of uric acid in the bloodstream. The condition typically strikes the big joint on the big toe. It has also been known to strike the knees, elbows, fingers, ankles and wrists—generally anywhere that has a functioning, moving joint.

The high level of uric acid in a person’s bloodstream creates the condition known as hyperuricema—the main cause of gout. Genetic predisposition occurs in nine out of ten sufferers. The children of parents who suffer gout will have a two in ten chance of developing the condition as well. 

This form of arthritis, being particularly painful, is the leftover uric acid crystallizing in the blood stream. The crystallized uric acid then travels to the space between joints where they rub, causing friction when the patient moves. Symptoms include: pain, redness, swelling, and inflammation. Additional side effects may include fatigue and fever, although reports of these effects are very rare. Some patients have reported that pain may intensify when the temperature drops, such as when you sleep.

Most cases of gout are easily diagnosed by a podiatrist’s assessment of the various symptoms. Defined tests can also be performed. A blood test to detect elevated levels of uric acid is often used as well as an x-ray to diagnose visible and chronic gout.

Treatment for gout simply means eliminating symptoms. Non-steroid anti-inflammatory drugs or NSAIDs (Colchicine and other corticosteroid drugs, etc.) will quell the redness, the swelling, and the inflammation. However, managing your diet, lifestyle changes, and using preventative drugs are all helpful toward fully combating the most severe cases.

 Those that lead an inactive lifestyle are at a higher risk for gout. Any amount of exercise decreases the probability of repeat encounters with the condition. Reducing your consumption of red meat, sea food, and fructose-sweetened drinks also reduces the likelihood of chronic gout as well.

Ingesting Vitamin C, coffee, and particular dairy products can help with maintaining a healthy lifestyle. There are new drugs out on the market that inhibit the body’s production of uric acid-producing enzymes. However, reducing or eliminating your overall levels of uric acid is the best remedy to ensuring you lead a gout-free life.

Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.

A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.

Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.

Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.

If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.

The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.

Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.

Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound.  To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.

To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
