According to WebMD, the first symptom of a blood clot inside the calf, also known as a deep vein thrombosis, varies from person to person. Common symptoms include calf pain, weakness, swelling or the appearance of bulging surface veins. Deep vein thrombosis can also be present without any symptoms. This is dangerous, because the blood clot can break free and travel to block more critical blood vessels.
