Anyone who has worn shoes has, most likely, at some point developed a blister. Blisters are pockets of fluid that form between the top layer (epidermis) of skin and underlying layers of skin due to friction, heat, chemical, or other damage to the epidermis. A blister can sometimes darken when blood from broken vessels mixes with the blister’s normally clear serum. This is known as a blood blister. Newer blood blisters are usually red and, as time progresses, can turn to darker shades of red, purple, or even black. Blood blisters can form on your feet in areas that have been under extreme pressure or friction, or where the skin has been pinched without any breakage in the skin. Blood blisters are usually nothing to worry about. However, if you have a reoccurring blood blister, or one that feels warm or has red streaks radiating away from it — or if the blister appears suddenly without any apparent cause — it is wise to make an appointment with your podiatrist for an evaluation.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact the foot specialists of NYC Foot & Ankle Center. Our doctors can provide the care you need to keep you pain-free and on your feet.
Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often lead to pain.
What Are Foot Blisters?
A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.
How Do Blisters Form?
Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.
Prevention & Treatment
It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.
