What are the symptoms of a blood clot in the calf?

Deep vein thrombosis (DVT) in the calf typically manifests with specific symptoms that can alert clinicians to the condition. Commonly, individuals may notice unilateral swelling—where one calf is significantly larger than the other. This swelling is often accompanied by tenderness and warmth in the affected leg. Some may also experience a persistent, cramp-like pain in the calf, which can be mistaken for a simple muscle strain. The skin over the area may appear red or discolored.

Medical literature highlights that these symptoms are often more pronounced after periods of inactivity, such as long flights or bed rest. Clinicians also consider risk factors such as recent surgery, trauma, or a personal or family history of blood clots when evaluating for DVT. Anyone with concerns about symptoms suggestive of a blood clot in the calf should discuss their specific situation with their healthcare provider.
