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.

Bunions are large bony bumps at the base of the big toe. Medically known as hallux valgus, a bunion is a misalignment of the metatarsophalangeal joint, or big toe joint. The misalignment will generally worsen with time if left untreated.

The exact cause of bunions is unknown, with genetics seen as a potential cause. High heels and poorly-fitted footwear, rheumatoid arthritis, and heredity all seem to be potential factors behind the exacerbation of bunions. Women have been found to be more likely to develop bunions in comparison to men.

Bunions do not always produce symptoms. The best way to tell is if the big toe is pushing up against the next toe and there is a large protrusion at the base of the big toe. You may or may not feel pain. Redness, swelling, and restricted movement of the big toe may be present as well.

Podiatrists use a variety of methods to diagnose bunions. If there are symptoms present, podiatrists will first consider that it is a bunion. If not, a physical examination will be conducted to check function of the big toe. Finally, an X-ray may be taken to view the extent of the bunion and confirm it is a bunion.

Typically, nonsurgical methods are used to treat bunions, unless the bunion has become too misaligned. Orthotics, icing and resting the foot, roomier and better fitted shoes, taping the foot, and pain medication are usually utilized first. If the bunion doesn’t go away or causes extreme pain, surgery may be required. Surgeons will either remove part of the swollen tissue or bone to straighten the toe out.

If you have a bunion, it is recommended to see a podiatrist. The longer it is left untreated, the worse it may get. Podiatrists can properly diagnose and treat a bunion before it gets worse.

Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures. 

Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.

The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.

The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.

A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.

If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.

Your feet endure a great amount of stress each day from constantly allowing us to move around. It is important to stretch your feet to help prevent them from becoming injured. Your toes may easily deform into unhealthful positions if they are not stretched.

One of the most common reasons for toe deformities are the shoes you may be wearing. Shoes that are too tight may fold and shift the toes out of place. Heeled shoes may also push your toes upward. Forcing your toes into an unnatural position which may cause the muscles to tighten and prevent them from reverting to normal length. Another common reason is improper use of foot muscles. Many people fail to use the muscles in their feet or toes when they walk. Lastly, the positioning of your feet while walking may also cause toe deformities. If you walk with your feet facing outward, your “push-off” phase is on the side of your big toe instead of the bottom of your foot. This may cause the big toe to eventually tighten into a new shifted position.

There are many reasons why stretching your toes may be helpful. One reason is that healthy spacing may aid in avoiding calluses and other injuries that are caused by rubbing.  Stretching will also prevent you from developing toes that curl, hammertoes, or bunions.

A great way to stretch your toes is to place them in your hands and bend them all downward; this will help you stretch the top of your foot. Next, you should repeat this process but instead bend them upward enough to feel a nice stretch in the bottom of your foot. You should then try to pull each toe apart from the next and pull any toes that are bent upward until they are back downward.

If you are looking to practice stretching your entire foot, you can try a towel stretch. This is done by sitting on the floor with your legs in front of you. Take a towel and wrap it around your toes. Afterward, pull the towel toward you with your toes and hold this position for 15 to 30 seconds before releasing. Practice this stretch for three sets. Another stretch your feet are towel lifts. This is done by sitting in a chair and trying to pick a towel up from the ground with your toes. Try lifting the towel with your little toes for five sets before switching feet.

If you are an athlete, or exercise often, it is especially important for you to practice stretching your feet. Those who suffer from foot pain caused by poor footwear, plantar fasciitis, or long hours of standing at work may also benefit from foot exercises.
