Blood clots in the legs, or deep vein thrombosis, can cause pain in the calf, swelling, redness, and a leg that is hot to the touch. Another sign is that lifting your foot/toe of the affected leg causes severe pain.
A blood clot in the leg obstructs the circulation of blood from the lower body back to the heart. This results in symptoms such as swelling, pain, redness, warm to touch, blue or white discoloration of skin, and leg cramps.
A blood clot in the leg can cause you to lose your pulse in the leg. In addition, the leg will get cold and clammy. Eventually, if you do not see a doctor, the leg will start to turn gray and then later a dark bluish-brown. Eventually the leg will turn black and need amputation.
Typically, the area will be swollen, red, and painful. The more common sign that may indicate a clot is that the area may be unusually warm or even hot.
