**7 Signs of a Blood Clot and What to Do Next**

Blood clots can be life-threatening if not treated promptly. Here are 7 signs to watch for:

1. **Swelling** in one leg, often with warmth and redness.
2. **Pain or tenderness** in the affected area, especially when standing or walking.
3. **Sudden shortness of breath**, chest pain, or coughing up blood (indicating a possible pulmonary embolism).
4. **Unexplained pain or swelling** in the arm or leg.
5. **Rapid heart rate** and dizziness, especially if accompanied by breathing difficulties.
6. **Cold skin** on one side of the body.
7. **Skin discoloration**—either a pale or bluish tint to the affected area.

**What to Do Next:**
If you suspect a blood clot, seek medical attention immediately. Call emergency services if you experience symptoms of a pulmonary embolism, as it can be fatal. Early intervention is key to preventing serious complications like stroke or organ damage.
