7. A Throbbing Sensation
Some people with DVT report a distinct, rhythmic throbbing sensation in the calf or thigh. This throbbing can be uncomfortable and is a sign that blood is struggling to pump past the blockage.
8. Pain When Bending the Foot
Medical professionals sometimes look for a sign called Homan’s sign. This is when pain in the calf sharply increases when you flex your foot upward (pulling your toes toward your shin). While not a definitive diagnostic test on its own, it is a common symptom of a deep vein clot.
9. Swollen, Hard Veins
You may be able to see or feel the affected vein just beneath the surface of the skin. A vein with a clot in it might feel thick, hard, or like a stiff cord, and it will likely be very sensitive or sore to the touch.
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.
