What is the main vein in the leg?
80241
There are two major arteries in the leg....the Femoral which extends from above the knee through the top of the thigh and the Tibial which extends from the femoral through the lower leg....and there are three major veins in the leg and foot...the Tibial which runs from the feet to the thigh..the Saphenous and Femoral which both run from knee to pelivs through the thigh.

No permanent cure.  Surgery removes the vein that you see and usually the one behind it (which is actually the bad one).  I had one leg done and I am very happy.  They only had to remove 3 veins.  sshe probably has too many veins involved and it would be dangerous for her should she need any heart surgery in the future.  (they take those veins from her leg).  \nIf the varicosity is small I don't understand why surgery is not recommended.  There is also laser surgery.  If varicose veins are hereditary and/or if she is on her feet all day in the wrong shoes, removal will only be temporary.  Mine are hereditary and I am on my feet all day (in sneakers) and I expect that at some point I will have more.  So far so good.  It's been 4 years.  And no sign of them yet and my legs feel (and look) great.

you may have poor blood circulation in your leg

the average person has about 10 pints of blood in them, as for   being held in the thigh ? are you asking about the artery located in the upper thigh/groin area? If a major artery is cut its not about how much, but time as the blood is pumped/bleeds out at a very fast rate. If you are asking about swelling due to retention it is most likely that it is fluid and not blood that is causing this.

Phlebitis is the inflammation of a vein, usually in the legs. The inflammatory process may produce redness, warmth, pain and swelling along the vein. If it is accompanied by fever, there may be an infection. Has she had a dr check it? If it is a large area of redness an swelling, it may be cellulitis. She would need to see a dr.

Hemangioma in the leg is a very rare site of the body to appear. but its possible. its enlargement of a bunch of blood vessels. which if traumatized causes lots of bleeding.

Blood does go to your feet.  But your veins have little valves that act like trap doors.  They let blood go through then block it from going back down.  This makes it so the blood doesn't pool as bad in your veins and feet.  However if you aren't using your legs, by moving around and such, then the blood will pool up more.  This leads to swollen legs and feet.  To test this, just hang your feet in the air for awhile, even while just sitting on a swing or something.  After awhile, if you jump down you'll get a shock in your feet from the blood being forced into your capillaries and veins.  \nThis explains why one needs to excercise their legs while on long flights, or you'll get swollen feet and could develop blood clots.

You have not mentioned whether it at rest or while walking. Main causes leading to progressive narrowing of the major arteries of the legs due to smoking, high blood pressure, diabetes and hyperlipidemia( High cholesterol deposit in the blood vessels).  Rest, if presence of rest pain. No smoking.  Reduce weight if you are obese. Skin should be protected from injury, shoes should be comfortable. Avoid tight garters.  Trim nails carefully. Avoid siting with legs crossed.  I f the skin is dry apply oil at night and dusting powder at day. Control fungus infections. Control high cholesterol diabetes, and blood clotting with medicines.   Till you get pain walk slowly up to that point several times daily.Warm environment is a necessity.    But do not apply warmth to the legs.   Active & Pasive leg exercise should be done. If necessary drugs should be taken .  I f all these fail surgery may be necssary.

You have an artery on both sides and a vein on the other (jugular) same as all parts of your body. One takes blood to the heart (vein) one back into the body full of oxygen (artery)

Veins carry deoxygenated blood from the organs and tissues back to the heart.\nDeoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part which drains the portal cyrculation too full with nutrients to nourish the body.

not necessarily...it could just be fluid retention. Your legs could be building up fluid throughout the day and at night with you lying flat it disperses. Is your leg hot and red looking and tight...this could be a sign of something more sinister...DVT.....either way if you are concerned go to your GP and get it checked to put your mind at rest if nothing else.

You need to call a doctor ASAP.  Pain in the calf and swelling of the leg could be Deep Vein Thrombosis (DVT).  It probably won't be, but it could also be a circulatory or vascular issue that you should have adressed.  Call your personal doctor, ask to speak with a nurse and tell them your symptoms.  They may refer you directly to an urgent care or they will run down a list of questions to 'triage' you and decide when and if you need to come in.  It can't hurt to call if nothing else, for peace of mind.

You might be experienceing sciatica.\n\nThe sciatic nerve is a large nerve that runs down the lower limb. It is the longest single nerve in the body.\n\nArising from the lower part of the sacral plexus, the sciatic nerve enters the gluteal region by the greater sciatic foramen of the hip bone.\n\nIt continues down the posterior compartment of the thigh, until it separates into the tibial nerve and the common peroneal nerve. The location of this division varies between people.\n\nPain along the sciatic nerve is called sciatica.

It could be a blood clot - an extreme case of Cellular thrombosis where the superficial veins are swollen blocking the circulation of blood to and from the lower parts of the leg partially. Need to wear either a crepe bandage or a surgical stocking and consult a doctor who will surely suggest a ultrasound sonography test to determine the exact location of the clot.

My mother-in-law got them zapped with lazor treatments.  I'm not sure what the actualy treatment is called, but she had them done a few weeks in a row and now her legs are vericose veins-free.  Check with your doctor.\n\nP.S. - She says it didn't hurt

You probably need to have this checked by a doctor.  \n\nDo you have varicose veins?  They are one of the more common causes of the feeling of heaviness in the legs.  \n\nThis site discusses various veins.
