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.

Hammertoe is a foot deformity that occurs due to an imbalance in the tendons, muscles, or ligaments that are responsible for holding the toes in their normal position. This condition may be caused by poor footwear, foot structure, trauma, and disease. The most common solution for hammertoe is to relieve the pain by changing your footwear and wearing orthotics. In severe cases, surgery may be required.

The shoes that are most likely to cause hammertoe are high heeled shoes or shoes that are too tight in the toe box. Tight shoes will force your toes to crowd together in a curled position. This position will likely continue when you take your shoes off. Another cause is trauma. When you stub your toe, you are increasing the chance that you will develop hammertoe.

There are risk factors that may make you more likely to develop this condition. Women are more likely to have the condition compared to men, and it is also more likely to appear in those who are older in age.

Many different foot problems can be avoided by wearing shoes that have adjustability, adequate toe room, and low heels. Furthermore, if you want to buy new shoes, you should look to purchase them at the end of the day and make sure you know your correct size. The importance of buying shoes at the end of the day is that your feet swell as the day progresses. You should also ensure that you are wearing your correct size because your shoe size may change as you grow older.

To diagnose someone with hammertoe, your podiatrist will need to conduct a thorough examination of your foot. Your doctor may even order an x-ray to evaluate the bones and joints of your feet and toes.

If you have hammertoe, your podiatrist may recommend that you wear shoes that fit you better along with inserts to place inside them. Additionally, he or she may suggest special exercises for you to perform to stretch your toes. One helpful exercise it to pick up marbles with your feet or crumple a towel with your toes.

Prior to meeting with your podiatrist, it will be helpful to make a list of all the symptoms you are experiencing. You should also make a note of medications you are taking and important personal information about your medical history.

Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening.  The fungal infection itself occurs beneath the surface of the nail.  Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail.  If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk. 

The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms.  Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails. 

Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes.  Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential.  Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.

Fungal nail treatment may vary between patients and the severity of the condition.  Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections.  Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications.  Debridement, or the removal of diseased nail matter and debris, may also be performed.  In more severe cases, surgical treatment may be needed.  In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed.  In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.  

Trauma to the foot, especially the toes, can occur in many ways. Banging them, stubbing them, or dropping something on them are a few different ways this trauma can occur. Given the fact that toes are positioned in front of the feet, they typically sustain the brunt of such trauma. When trauma occurs to a toe, the result can be a painful break or fracture. Another type of trauma that can break a toe is repeated activity that places stress on the toe for prolonged periods of time.

Broken toes can be categorized as either minor or severe fractures. Symptoms of minor toe fractures include throbbing pain, swelling, bruising on the skin and toenail, and the inability to move the toe with ease. Severe toe fractures require medical attention and are indicated when the broken toe appears crooked or disfigured, when there is tingling or numbness in the toe, or when there is an open, bleeding wound present on the toe.

Generally, a minor toe break will heal without long-term complications. However, it is important to discontinue activities that put pressure on the toe. It is best to stay off of the injured toe and immediately get a splint or cast to prevent any more additional movement of the toe bones. You can also immobilize your toe by placing a small cotton ball between the injured toe and the toe beside it. Then, tape the two toes together with medical tape. Swelling can be alleviated by placing an ice pack on the broken toe directly as well as elevating your feet above your head.

Severe toe fractures may be treated with a splint, cast, and in some cases, minor surgery, especially when the big toe has been broken. Due to its position and the pressure the big toe endures with daily activity, future complications can occur if it is not properly treated. Pain associated with minor toe fractures can be managed with over-the-counter pain medications. Prescription pain killers may be necessary for severe toe fractures.

The healing time for a broken toe is approximately four to six weeks. In severe cases where the toe becomes infected or requires surgery, healing time can take up to eight weeks or more. While complications associated with a broken toe are immediately apparent, it is important to note that there are rare cases when additional complications, such as osteoarthritis, can develop over time. You should immediately speak with your podiatrist if you think you have broken your toe due to trauma. They will be able to diagnose the injury and recommend the appropriate treatment options.
