Here’s what to watch for:
🚨 1️⃣ Swelling in One Leg (Especially Sudden)
Possible cause: Deep Vein Thrombosis (DVT) — a blood clot in a deep vein.
Watch for:
-
One leg noticeably larger than the other
-
Warmth, redness
-
Pain or tenderness in the calf
⚠️ This is urgent. A clot can travel to the lungs (pulmonary embolism).
🔥 2️⃣ Burning, Tingling, or Numbness
Possible cause:
-
Nerve damage (often related to diabetes)
-
Sciatica
-
Vitamin deficiencies
If it’s persistent or worsening, get checked — especially if you have blood sugar issues.
🦵 3️⃣ Leg Pain While Walking That Improves With Rest
Possible cause: Peripheral Artery Disease (PAD)
This happens when arteries narrow and reduce blood flow.
Other signs:
-
Cold feet
-
Shiny skin
-
Weak pulse in feet
PAD increases risk of heart attack and stroke.
🌡️ 4️⃣ Red, Warm, Painful Area on the Leg
Possible causes:
-
Infection (cellulitis)
-
Blood clot
If combined with fever or rapid swelling, seek medical care.
⚡ 5️⃣ Severe Sudden Leg Pain
Possible causes:
-
Acute artery blockage
-
Muscle tear
-
Nerve compression
If leg becomes pale, cold, or numb → emergency.
🩸 6️⃣ Non-Healing Sores or Ulcers
Possible causes:
-
Diabetes-related circulation problems
-
Venous insufficiency
-
PAD
Slow-healing wounds are a red flag for poor blood flow.
🧊 7️⃣ Cold or Pale Leg Compared to the Other
May indicate reduced blood supply — especially if paired with pain.
🟣 8️⃣ Visible Bulging Veins With Pain
Likely varicose veins — usually not dangerous, but:
-
If painful, swollen, or hardened → get evaluated.
🚩 Seek Immediate Care If You Notice:
-
Sudden one-sided swelling
-
Chest pain + leg pain
-
Shortness of breath
-
Leg turns blue, pale, or very cold
💡 Don’t Ignore Risk Factors:
You’re at higher risk if you:
-
Sit for long periods (travel, desk job)
-
Smoke
-
Have diabetes
-
Have high blood pressure
-
Have a history of blood clots
