Diabetic foot ulcers can be difficult to effectively treat due to inhibited blood flow to the extremities, which is why it is so important to work to prevent them or treat them at the earliest stage when you notice one is developing. In order to intervene at an early stage, we need to know the first subtle signs that the conditions are right for a diabetic foot ulcer. In today’s blog, we share some of the early warning signs of diabetic foot ulcers so that you can begin treating them sooner.
Early Signs Of A Foot Ulcer
If you have diabetes, it’s imperative that you perform regular foot checks to look for the early warning signs of an ulcer or other foot issues. Here are some of the first hints that a foot ulcer may be developing:
1. Drainage/Sock Discoloration – One of the first signs for a diabetic foot ulcer that you may notice is on your sock. If you begin to notice yellow or clear discoloration on your sock above an area where you may have a small irritation, it’s a sign that the body is attempting to repair a problem in the area. If the area can’t get enough oxygenated blood, the wound may worsen and the drainage will get worse. If you notice fluid buildup or some discharge on your sock, take a closer look at your foot.
2. Redness – Redness is also a sign that the body is attempting to address an issue, so if a certain spot on your foot is starting to get red or darker in color, it’s a sign that the area could be susceptible to ulcer formation.
3. Swelling – If an area of your feet or your whole foot has started to swell a bit, it’s a sign that fluid is pooling in your foot and that healthy blood flow in and out of the area may not be all that effective. This means it will be harder for wounds or sores to heal. If you have any irritations or sores on your feet and they are swollen, know that the environment is right for a foot ulcer and you should take some mitigation steps.
4. A Foul Smell – Finally, sometimes the fluid discharge at an irritation site is hard to see if it’s clear, but it may produce a foul-smelling odor. If your feet or socks are beginning to carry an unnatural odor, it could be from fluid release through a wound on your foot that is susceptible to ulcer formation.
These are just four of the early signs of foot ulcer development. Symptoms become more apparent as the condition gets worse, so it’s important to look for these subtle signs as opposed to more obvious indications like scabbing, escharing, foot discoloration or gangrene.
