The legs are primarily affected, with 4–10% of DVT occurring in the arms. [11] Despite the signs and symptoms being highly variable, [ 5 ] the typical symptoms are pain, swelling , and redness. However, these symptoms might not manifest in the lower limbs of those unable to walk. [ 22 ]

If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
[3] [4] [5] VTE can present with various symptoms, such as painful leg swelling, chest pain, dyspnea, hemoptysis, syncope, and even death, depending on the location and extent of the thrombus.
