Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.

The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.

The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.

If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.

Though cuboid syndrome predominately affects athletes, non-athletes can suffer from it too. Cuboid syndrome is also called cuboid subluxation or cuboid fault syndrome, and occurs when a joint or ligament near the cuboid bone of the foot becomes damaged, or when the bone itself is dislodged from its natural position. Pain may be persistent, or come and go, and it is usually marked by the outside of the foot. Cuboid syndrome, unless severe, can be difficult to diagnose. A doctor will likely ask questions about how long the pain has been present, and will apply pressure on the cuboid bone to determine the origin of pain.

There are a number of causes that can lead to the syndrome. Due to athletic activities, repeated stress placed on the foot can cause cuboid subluxation. Ballet dancers, runners, and other athletes often develop this condition. Basketball or tennis players may also develop this condition, as they place stress on their feet while moving side to side. Cuboid syndrome can often develop over time; however it can come out of a sudden injury as well. Over pronation, or other problems with feet, can exacerbate the condition if not corrected.

Among podiatrists, there is some disagreement about the treatment, as well as the definition of cuboid syndrome. Some see the injury as an injury to the ligaments located nearby the cuboid bone, while others believe it refers to the dislocation of the calcaneal-cuboid joint only. Treatment opinions differ as well. Although it can be treated by manipulation in order to reposition the bone, this must be done with extreme care in order to avoid injury. Some doctors, however, prefer treatment through the use of orthotic pads, designed to keep the bone in its place. Effectiveness of these treatments may vary, according to the severity of the injury.

When you experience side foot pain, it is important that you seek medical assistance. If a subluxed cuboid is caught and treated early, treatment is usually successful, and individuals may begin activities such as sports when the pain subsides. If left untreated, the pain will worsen, and the condition could cause permanent damage.
