3 Foot Problems That Could Cause Infection
It’s easy to ignore a little bit of foot pain because we are too busy to deal with it. But here’s the thing: when the skin on your feet gets compromised, that original foot problem, like an ingrown toenail, can let in germs that your feet would normally keep out. We at New Jersey Podiatric Physicians & Surgeons Group are here to tell you which foot conditions are the most likely to lead to such secondary infections.
Ingrown Toenails
Let’s start with the classic ingrown toenail. You might think it is just a stubborn nail that needs a quick trim, but when that sharp edge pierces the skin around your toe, it creates a direct path for bacteria to enter.
This is why you often see redness, swelling, and eventually pus around the nail. If you try to do it yourself with a pair of unsterilized clippers or tweezers, you are basically doubling the risk of a secondary infection.
Once the bacteria get under the skin, it can lead to a condition called paronychia, which can be incredibly painful and difficult to clear up on your own.
Cracked, Bleeding Heels
Then there is the issue of cracked heels, which people often ignore until they start to bleed. During the winter, especially, the skin on your heels can get so dry that it loses its ability to stretch. Eventually, it splits open and creates deep fissures.
Since your feet are constantly in contact with socks, shoes, and various floors, those cracks become perfect entry points for bacteria. This can lead to cellulitis, which is a serious skin infection that makes the area feel hot and swollen.
If you notice a red rash spreading up from your heel, you could be dealing with a complication that needs prompt attention.
Un-popped Blisters
We have all dealt with a blister after wearing the wrong shoes for a long walk, but how you handle it determines if it stays a painful annoyance or becomes a medical problem.
A blister is your body’s way of creating a natural, sterile bandage for the raw skin underneath. When you pop a blister, you are removing that protection and exposing vulnerable tissue to whatever is lurking in your footwear.
If the fluid inside turns cloudy or you notice red streaks coming from the area, you are looking at an infection that started from a simple friction rub.
