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.

Many pregnant women complain about foot pain while they are expecting. Foot pain can primarily be caused by weight gain and hormonal changes taking place in the body. By understanding how pregnancy impacts the health of a woman's feet, a pregnant woman can take action to keep her feet as healthy and comfortable as possible.

Because a woman's weight changes during pregnancy, more pressure is brought to bear on both the legs and the feet. This weight shift can cause two major foot problems: over-pronation, also known as flat feet, as well as edema, which is swelling of the feet. Over-pronation occurs when the arch of the foot flattens, causing the foot to roll inwards when the individual is walking, and can aggravate the plantar fascia tissues located along the bottom of the feet. If these tissues become inflamed, a pregnant woman can experience pain in the heel of the foot as well as severe foot pain while walking or standing. Swelling of the feet, or edema, often occurs in the later stages of pregnancy. It is caused by slow circulation and water retention, and may turn the feet a light purple color.

To keep feet in good health and prevent over-pronation, pregnant women should avoid walking barefoot and be sure they are wearing shoes that offer good arch support. A device known as an orthotic can be added to regular footwear in order to provide additional support for the feet during pregnancy. Any expectant mother whose feet hurt should first check to see if the shoes she is wearing are old, worn out and not offering the proper support necessary for distributing the weight of her body during pregnancy.

To treat edema of the feet, a good start is to wear quality footwear which offers support and good circulation. Keep feet elevated whenever possible by using a foot stool while seated. Stay well hydrated by drinking plenty of water to prevent water retention in the feet. Any swelling that occurs in only one foot should be examined as soon as possible by a doctor.

Good foot health during pregnancy can help expectant mothers avoid foot pain that leads to other health problems. Massaging the feet and doing regular gentle exercise like walking aids foot health by contributing to good circulation. Supportive shoes are also a good investment that will support foot health during pregnancy.

When the weather heats up, you may want to start wearing flip-flops. However, it has been proven that these are not the ideal shoes in terms of preserving the health of your feet.

Flip flops are known to expose your feet to different types of bacteria and fungal infections. When you wear your flip flops in public, you are exposing them to staphylococcus which is a skin-irritating bacterium. Athlete’s foot is also highly contagious and can be spread when you walk around nearly-barefoot.

Another harmful effect of wearing flip-flops is that they develop blisters on the feet. This is because the thin strap rubs against the skin with each step taken. Unfortunately, when blisters pop, they cause you to be more vulnerable to pathogens you pick up by having your feet exposed.

These shoes may also cause “shooting pains”. If you have flat feet, you need arch support to keep your knees, hips, and back in alignment. If you wear flat shoes, your joints are forced to compensate which can cause injuries throughout the body.

If you constantly wear flip-flops, you should avoid doing so as they can lead to many problems for your feet. If you are experiencing any of these foot issues, you should seek help from a podiatrist right away.
