Foot blisters are a common issue often caused by friction from shoes or prolonged activity. While most blisters heal on their own and do not require medical attention, proper care is essential to prevent complications, such as infection. Blisters form when the skin is subjected to repetitive rubbing, leading to the separation of skin layers and the accumulation of fluid between them.

Typically, new skin will form beneath the blister, and the fluid is reabsorbed by the body. It is generally advisable not to puncture a blister unless it is large, painful, or likely to be further irritated. If you do need to pop a blister, use a sterilized needle, clean the area thoroughly, make a small puncture, and gently drain the clear fluid. Afterward, apply antibiotic ointment and cover the area with a sterile dressing to protect it from infection. It’s important to keep the skin over a broken blister intact, as it serves as a protective layer for the new skin underneath.

If the fluid inside the blister appears white or cloudy, this may indicate an infection, and you should seek medical attention promptly.

Preventing Foot Blisters:

• Gradually break in new shoes to avoid excessive friction
• Apply petroleum jelly or adhesive bandages, such as moleskin, to areas prone to rubbing before blisters form
• Ensure you wash and dry your feet daily to reduce the risk of bacterial infections
