Would this be a varicose vein or a blood clot?Which is more painful?

Is a blood clot always deep in the limb, and a varicose vein either towards just under the skin or deeper inward?

They are different. Veins have valves that help the blood fight gravity. The blood flow through a vein is weaker than through an artery so when the blood flows through the vein a valve closes behind it so the blood can make it's way back to the heart. Varicose veins occur when the valve in the vein becomes weak and blood pools in that area of the vein.

A is blood clot is a mass of blood cells and blood components that form to stop the bleeding that occurs when a blood vessel is injured. When a blood vessel is broken, platelets in the blood become sticky and clump together at the site of the injury. They begin to form a mass to stop the flow of blood.

There may be no obvious symptoms of a blood clot. When symptoms do occur, they often appear suddenly, and point to the location of the clot. Extreme dizziness that occurs without warning can indicate a clot in a cerebral artery. Sudden complete or partial blindness in one eye could indicate a clot within the retinal artery. A hard blue bulge in a vein, or unexpected pain in an arm or leg, along with numbness, weakness, or another sign that blood is not reaching the area, could indicate a blood clot. Blisters or ulcers on the skin may occur as well. A clot in an artery near a major organ like the heart or lung will produce pain or decreased activity in that organ. Gangrene (death of tissue) may occur if blood flow to a region is blocked for an extended period of time.

I'd have to say a blood clot is definitly more painful and dangerous than a varicose vein. Source(s): http://www.healthline.com/galecontent/bl...

I'd be getting to the doctor to get that checked. If it's a blood clot and moves to the lung or heart, you could die or have a stroke. It isn't worth guessing over. Better to make a trip for nothing than to stay home and find out the hard way.

Take care

Blood clots can be very painful. Vericose veins change in size and color when you elevate the area as the blood drains out. Blood clots are serious and need to be taken seriously. Vericose veins are a long term annoyance. I'm not a doctor. It's always best to ask a doc if you think you are at risk.
well, a blood clot can kill you, so i'd go with that one being more more painful.
Blood clots are painful and cannot be seen on the surface of the skin because they are usually deep (hence the name deep vein thrombosis or DVT) within a vein of a limb. Blood clots cause the limb to swell.

Varicose veins are usually painless, there are some that can cause pain but not as severe as a blood clot, and can be seen on the surface of the skin.
