The most common causes of blister include: a faster pace, a longer distance, new or poor tennis shoes, humidity, or damp feet. Blisters are uncomfortable and bothersome because they are brought on by friction, which occurs when socks or footwear brush against the skin. Calluses and blisters are both signs that your body is protecting itself from injury to the feet. A callus is painfully rigid skin, whereas a blister is skin that is fluid-filled and frequently painful.
According to definition, a blister is an area on the stratum corneum, or uppermost layer of skin, that thickens abnormally and produces a protective layer in reaction to repetitive rubbing.
Blisters happen when the upper layers of the skin split from the lower layers owing to extreme pressure, which is typically brought on by wearing shoes that are too small or too tight. The intercellular fluid enters the space between them through a small opening, forming a fluid "balloon" as a result. When shoes are overly tight or not used, blisters most frequently develop.
Additionally, large or worn-out socks and greater leg sweating can hasten the development of blisters. It is crucial to know how to correctly treat blisters because they are a common occurrence in practically everyone's life.
How to prevent formation of Blisters?
Blisters are something we can avoid with a little attention and effort. The simplest solution is to take daily care of your feet's skin; dry, sweaty feet are more prone to blister development, and frequent use of moisturizing creams or lotions softens the skin and keeps normal levels of moisture in it. As a result, avoid being lazy and massage the affected area, for instance, after each shower.
What shouldn't be emphasized as much—but shouldn't be ruled out—is the necessity of selecting the right tennis shoes and socks. Always buy half a size to a size larger than footwear when purchasing to ensure there are no blisters or squeezes anywhere. Invest in some thicker toe and heel running socks with synthetic materials that absorb perspiration.
It is best to apply a patch to a blister as soon as one appears to stop it from getting worse. To avoid potential infection, do not pierce the blister once it has fully grown and is filled with fluid.
Instead, drain the excess fluid.
Avoid touching the blister that forms because it will disappear on its own very fast. Never rip the skin from a blister when it ruptures because the skin covers and protects the injured region.
Cleaning, sanitizing, and applying an antiseptic lotion to the affected region are essential. Make sure to cover the blister with a patch if it is in a location where it might be damaged or subjected to additional pressure. You can get specialized anti-callus patches at pharmacies that include a gel core that protects the wound and reduces discomfort while hastening the healing process.
Leave the blister uncovered if it won't be subjected to more pressure so that it can continue to heal. This is especially true before bed. At least twice daily, or more frequently as necessary, change the patch. Keep the blister area tidy and always covered because it will inevitably break.
Additionally, avoid tearing the blister when it dries up and new skin starts to grow because doing so will prevent the blister and the wound it caused from fully healing.
Be careful to see a doctor if the blister becomes red and infected around and on it in order to avoid subsequent issues that could result in skin or blood infections.
Stop touching the blister, keep it clean, control swelling, apply a proper patch to the blister, and identify when you need to see a doctor.
