10. Shortness of Breath and Chest Pain (The Danger Zone)
If a clot breaks loose and travels to your lungs, it becomes a Pulmonary Embolism (PE). This is a medical emergency. If your leg symptoms are accompanied by—or suddenly replaced by—any of the following, call 911 immediately:
Sudden, unexplained shortness of breath.
Sharp chest pain that gets worse when you take a deep breath or cough.
A rapid heart rate.
Coughing up blood.
Feeling dizzy, lightheaded, or fainting.
What to Do If You Suspect a Blood Clot
Do not try to “massage it out” or wait to see if it gets better. Massaging a DVT can actually cause the clot to break loose. If you experience the localized leg symptoms described above, go to urgent care or the emergency room immediately. An ultrasound is the most common way doctors will quickly and painlessly confirm if a clot is present.
