3. Blisters
After the initial symptoms of redness, swelling, and tender nail beds occur, the next stop on the list is the development of pus-filled blisters on the edge of the nail bed, where the cuticle meets the skin. These blisters are small and may occur in clusters.
The blisters mainly form on the feet, as the swelling from the infection inflames the big toe. As the toe rubs on the inside of the shoe or sock, it spurs further irritation to the skin. As a result of the inflammation, the toe may form a blister, filled with clear fluid.
Medical experts have differing opinions on whether the patient should pop the blister or not. Some say that the patient should wait and let the blister disappear on its own, while others recommend popping it to relieve pain symptoms. However, popping the blister may release more toxins into the toe, and the bacteria may end up infecting the wound as well.
