Red legs can indicate several underlying conditions, ranging from mild to serious. It's crucial to consider accompanying symptoms like swelling, pain, and warmth to determine the cause.
Possible Causes of Red Legs:
-
Cellulitis: A bacterial skin infection causing a hot, swollen, tender, red leg. This requires prompt medical attention. Legs Matter provides further details on identifying and treating cellulitis.
-
Edema: Fluid buildup causing swelling, often in the legs and ankles. While not always red, edema can be accompanied by redness, especially if there is an associated inflammatory process. This can be a symptom of circulation problems. Banner Health offers more information on edema.
-
Venous Stasis Dermatitis: Blood pooling in the lower legs due to chronic venous insufficiency, leading to red, inflamed, and often itchy skin. Cleveland Clinic explains this condition in detail.
-
Gravitational Eczema (Varicose Eczema): A long-term skin condition common in those with varicose veins, presenting as a red, crusty rash on the lower legs. This is a skin-related issue, not usually responsive to antibiotics. The image in Figure 2 of an unspecified reference demonstrates mild gravitational eczema. NHS offers information on varicose eczema.
-
Tinea Pedis (Athlete's Foot): A fungal infection affecting the feet, which can sometimes spread causing redness on the lower legs.
-
Other Chronic Conditions: Various other chronic conditions can contribute to red legs.
-
Venous Leg Ulcers: These ulcers, often associated with poor circulation, can cause redness, swelling, and skin discoloration. NHS Inform describes venous leg ulcers.
Important Note: The provided references mention that redness in the legs can be accompanied by symptoms such as warmth, tenderness, swelling, and other skin changes (such as flaking or crusting). The intensity and location of redness, along with accompanying symptoms, help to distinguish between the various possibilities. "Red Legs" as a general term requires further investigation to pinpoint the specific condition.
