There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.

In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.

Heel pain can be difficult to deal with, especially if you do not know what the underlying cause is. If you ignore your heel pain, the pain can magnify and potentially develop into a chronic condition. Depending on the location of your heel pain, you have developed a specific condition.  

One condition is plantar fasciitis.  Plantar fasciitis is caused by the inflammation of the plantar fascia, or the band of tissue that connects the heel bone to the base of the toes. The pain from this condition is initially mild but can intensify as more steps are taken when you wake up in the morning. To treat this condition, medication will likely be necessary. Plantar fasciitis is often associated with heel spurs; both require rest and special stretching exercises.

There are various options your podiatrist may suggest for heel pain.  Treatment options for heel pain typically include non-steroidal anti-inflammatory drugs (NSAIDS), which may reduce swelling and pain. Other options are physical therapy, athletic taping, and orthotics. In severe cases of heel pain, surgery may be required.

Preventing heel pain is possible.  If you are looking to prevent heel pain from developing in the future, be sure to wear shoes that fit you properly and do not have worn down heels or soles. Be sure to warm up properly before participating in strenuous activities or sports that place a lot of a stress on the heels. If you are experiencing any form of heel pain, speak with your podiatrist to determine the underlying cause and receive the treatment you need.

One out of ten broken bones is reported to be in the feet. When an object crushes, bends, or stretches the bone beyond acceptable ranges, bones break. A break in the foot is either a fracture or a straight break.

The location of any break can tell you how the break happened. Toes, for instance, break typically as a result of something being kicked hard and with great force. Heel breaks almost always are a result of an improper landing from a tall height. Twists or sprains are the other two frequent occurrences. As with all usual breaks, they result from unexpected accident or sudden injury. As with stress fractures, breaks form as a process over time from repeated stress on already present cracks. Runners, dancers, and gymnasts are the usual athletes who receive this type of break. Stress fractures result from incredible pressure on the feet. It is no surprise these athletes bear the majority of reported fractures.

Pain, swelling, bruising, and redness are all indicative of the typical symptoms from a broken foot. Severe pain—to the point of not being able to walk—usually depends on the location of the break in the foot. Toes are on the lower scale of pain threshold, but heels are high, as are a few other particular bones. As the severity of the broken foot increases, symptoms like blueness, numbness, misshaping of the foot, cuts, or deformities will become apparent. These symptoms indicate the need to see a medical professional with access to an x-ray facility.

Prior to seeing a specialist, precautions should be taken to reduce pain and swelling. Elevate and stabilize the foot, and refrain from moving it. Immobilization of the foot is the next priority, so creating a homemade splint is acceptable. Keep in mind that while creating a splint, any increase of pain or cutting off blood circulation means that the splint should be removed immediately. Use ice to decrease swelling and relieve pain symptoms.

When dealing with a medical center, the patient should note that the treatment can vary. The treatment will depend on the severity of the fracture and the cause of the break. Crutches, splits, or casts are common treatments while surgery has been known to be used in more severe cases in order to repair the break in the bones. 

Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters.  Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.  

Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.

Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.

To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.  

The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.

Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.

Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
