Veins are responsible for returning blood to the heart. If the vein walls weaken or valves malfunction, blood may begin to collect instead of flowing efficiently. This can lead to enlarged and twisted veins, commonly known as varicose veins. They are most frequently seen in the legs, although they can also develop in the arms or other areas.
More noticeable veins can also be linked to certain medical conditions, such as:
• Phlebitis, where inflammation causes pain and swelling
• Chronic venous insufficiency, which can make the legs feel heavy or achy
• Deep vein thrombosis, a serious condition involving blood clots
• In rare cases, vascular changes related to liver disease or other organ issues
Additional Symptoms to Watch For
Changes in vein appearance combined with other signs may indicate a problem. Examples include:
• Persistent or unexplained swelling
• Areas of skin that feel unusually warm or tender
• Redness or discoloration spreading around the vein
• Veins forming new, unusual patterns on the chest or abdomen
If several of these symptoms occur together, medical evaluation is recommended.
