Varicose veins are the bluish colored, dilated veins which often give a pain sensation. These occur due to the weakness of valves present in the vein which give rise to pooling of blood in a specific place or backflow of blood.
There are several factors that cause Varicose Veins. Here is an insight into how the varicose veins develop.
The blood vessels that transport blood from all over the body to the heart are veins are. When a person is standing or in an activity that exerts pressure, his leg muscles would contract, causing blood from the lower body to be pumped to the heart through the veins., blood may seep back into the vein and collect there in case defects of these valves. As a result there is a state where blood advances towards the heart but then in the journey of upward movement, it tends to flow downwards. The collected blood then expands the vein and it becomes varicose.
The pressure in the veins rises, as time passes, progressively creating those veins to become inflated and varicose. However, this may take many years to happen. This backflow of blood is one of the reasons why a person has spider veins. Additional causes for the development of spider veins involve inherited factors, hormonal changes, and exposure to the sun.
Although the conditions for varicose veins to develop are largely unidentifiable, causes include congenially defective valves, pregnancy, and thrombophlebitis. High pressure created from prolonged standing within the abdomen may also make the condition worse or even supplement to one’s risk for its expansion.
Here are the symptoms by which you can understand that you have a varicose vein. Sometimes, varicose veins may not cause any pain. Signs you may have with varicose veins include:
- Veins that look bulging and twisted; often like wires on your legs
- Veins that are blue in color or have a purple hue to it.
- When there is a pain the signs and symptoms which occur, are underlying:
- Throbbing, burning, swelling or cramping of muscle in your lower areas of the leg.
- Heavy feeling in your legs or when you sense that your legs are aching.
- Worsened pain after standing or sitting for a long time.
- If you are bleeding from the veins.
- Prickling around one or more of your veins.
- Comparable to varicose veins, Spider veins are slightly smaller. Spider veins are located very near to the skin surface and are often blue or red.
So to sum it up if there are any changes in colour, or you can sense that the veins are harder, skin or skin ulcers near the ankle area or there is any kind of swelling, which can suggest you have a severe kind of vascular disease that needs immediate medical inspection.
