1. Persistent Leg Swelling Could Signal Circulation Problems
Occasional swelling in the legs or ankles isn’t unusual. Spending hours sitting during a long flight or standing all day at work can temporarily cause fluid to collect in the lower extremities.
However, swelling that persists or worsens may warrant medical attention.
Potential causes include:
- Chronic venous insufficiency
- Heart conditions affecting circulation
- Kidney disease
- Liver disorders
- Certain medications
- Problems involving the lymphatic system
If swelling affects only one leg, especially when accompanied by pain, redness, or warmth, immediate medical evaluation is important. In rare cases, these symptoms may indicate a blood clot requiring urgent treatment.
Pay attention to whether swelling improves overnight or remains constant regardless of activity.
2. Leg Pain During Walking May Indicate Peripheral Artery Disease
Do your legs ache when you walk but feel better after resting?
This pattern may point toward a condition known as peripheral artery disease (PAD).
PAD occurs when narrowed arteries reduce blood flow to the limbs. As muscles work harder during physical activity, they may not receive adequate oxygen-rich blood, resulting in discomfort.
Common symptoms include:
- Cramping in the calves
- Thigh pain during exertion
- Fatigue in the legs
- Pain that improves with rest
Peripheral artery disease shares risk factors with cardiovascular disease, including smoking, diabetes, high blood pressure, and elevated cholesterol levels.
Early diagnosis can help reduce complications and improve quality of life.
