Does a blood clot in the veins cause a cold leg?

No. Generally clots in the veins cause swelling and pain. The leg tends to have a normal or slightly warm.These clots can travel to your lungs with pain and shortness of breath. A clot in the artery diminishes blood flow to the legs and causes them to be cold and without pulses and with severe pain. Be checked out rapidly for either concern.
In short, no. In order for a limb to grow cold, the blood supply TO the limb needs to be cut off. This is most commonly is caused by the occlusion of the ARTERY, not the vein. The occlusion, or blockage, is often caused by a blood clot.
Not usually. Not usually, I would expect warmth from a venous blood clot. However a blockage in an artery could cause a cold leg. I see the appropriate tests are being done on your leg for diagnosis. Has a blood clot been found?

Can impact to the knee cause a blood clot in a vein in the upper calf? The impact was not hard enough to any structural damage to the knee

Ultrasound preferred. No, not really. The DITI scan helps look at injuries in the skin.

See answer. If the lumps are just under the skin they may be areas of superficial thrombophlebitis(or something else),in which case the area would be tender. Superficial thrombophlebitis isn't serious but blood clots in the deep veins(DVT) is. Clots in the deep veins won't be palpable just under the skin. Read more...
Possibly. Your description points to the presence of varicose veins which are enlarged veins on the surface that one can feel and can be mobile in nature. Clots in the deep veins cannot be felt. Varicose veins can indicate poor circulation. Chronic poor circulation can affect small distal vessels leading to neuropathic symptoms. If she has pain associated with these veins, they should be evaluated further. Read more...
