Why do badminton feet blister?

loves badminton has experienced blisters on the soles of their feet, and blisters also make our feet particularly painful. If the blisters burst, it will not only be very painful and affect our performance during exercise, but also worry about foot infection. So, what exactly causes blisters on our feet? Is it because the shoes are too tight? Socks too thin? Or are our actions not standard?

Why does playing ball make our feet blister?

Are blisters caused by repeated rubbing of the skin against another object . Common on the soles of our feet, the sides of the feet, and the toes. The tops of the blisters are rubbed off where the skin is thinner, such as the tops of the feet, creating abrasions. In thinner areas of skin, friction can cause abrasions to blister. Speaking of blisters while exercising, friction blisters occur when there is contact, pressure, and movement between the skin and what comes into contact with it (such as new or unfamiliar shoes rubbing against the heel). Shear forces lead to mechanical separation of the epidermal cell layers. The gap fills with fluid, forming subepidermal blisters. Blisters can form more quickly if the pressure and movement on the skin is severe or if the skin is damp . And playing badminton runs a lot. Emergency stops and quick turns are commonplace. The friction of the soles of the feet is very large. In addition, the soles of the feet sweat during the exercise, the feet are wet, the soles of the feet are softened, and the soles of the feet are exerted and rubbed for a long time. Foot blisters are formed due to the exudation of local tissue fluid .

There are two reasons why the feet are more prone to blisters:

To sum up, the reasons mentioned above are also related to the heavy moisture in the feet and the friction between the feet and the shoes. The reasons are as follows:

1. Badminton shoes do not fit well:

If the shoes are too tight, the soles of the feet will be squeezed when surfing the Internet or starting up, and if the shoes are too loose, there will be more chances of friction between the feet and the shoes during exercise. Shoes that are too tight or too loose can cause blisters on the soles of your feet. Shoes that are not breathable can also cause dampness on the feet, causing the skin on the soles of the feet to become soft and prone to blisters after friction.

Response: The shoes should be suitable for the feet and breathable. New shoes can be adapted to low-intensity training first. Do not play games and train at high-intensity when you are not used to them.

2. Socks are too hard to absorb sweat:

Some cotton socks have been worn for a long time, and the number of times of washing will increase, and they will become hard. Socks that are not breathable and sweat-absorbing can easily cause the soles of the feet to be too wet, slippery, and cause blisters.

Complications of friction blistering :

Intact friction blisters usually heal quickly without scarring. Healing is sometimes delayed. Problems may include:

Wound infection : This manifests as increased pain and redness around the blister/erosion, red streaks in the groin or armpit, and pus formation. Infections are more common in diabetics and immunocompromised individuals.

pyogenic granulomas occasionally develop at the site of the blister .

Scars from infection or deeper injury.

How can I better deal with friction blisters?

Friction blisters will heal on their own. However, dressings help prevent further damage. Innomed ® blister plaster can be used which promotes faster wound healing , provides the wound with a slightly acidic containment space that is conducive to wound healing, and prevents wound infection. If your blisters are too large , they can be punctured with a sterile needle. If you can , it's best to keep the top of the blister in place to reduce pain and reduce the chance of infection. If the top of the blister falls off and leaves an eroded skin surface, clean the wound carefully and apply a clean dressing.

Infected friction blisters or erosions may require topical antibiotics or antiseptics for several days. If cellulitis occurs, systemic antibiotics must be used. Antibiotics should not be used if the wound is not infected.
