How to detect early symptoms of lower extremity venous thrombosis

Early symptoms of lower limb venous thrombosis include leg swelling, soreness and pain, and changes in skin color. If similar symptoms occur, especially obvious manifestations on one leg, you should seek medical attention as soon as possible to get a clear diagnosis and avoid serious consequences.

The formation of lower extremity venous thrombosis is due to poor blood circulation in the veins, which causes blood to clot. In the early stage, it is often manifested as unexplained unilateral leg swelling, accompanied by a feeling of heaviness or tightness. Patients may feel pain in the calf or thigh, especially when walking or squeezing the local area. Some people will find that the skin of the affected limb becomes red or purple, and the skin temperature rises. Pain caused by light pressure on the calf muscle (Homan's sign) is also a common sign. Such symptoms are often easily confused with muscle strain or sprain, so special attention should be paid to the persistence, aggravation and unilateral characteristics of the symptoms. In severe cases, the thrombus may break off and cause pulmonary embolism, which manifests as critical signals such as chest pain, shortness of breath and even fainting.

To prevent further deterioration of thrombosis, you need to cooperate with the doctor to take treatment after diagnosis. Mild patients may receive drug thrombolytic therapy, such as oral warfarin, dabigatran or injection of low molecular weight heparin. For more severe thrombosis, consider inserting a venous filter to prevent the movement of the thrombus or removing the thrombus through minimally invasive surgery. In life, appropriately increasing lower limb activities such as walking or ankle joint activities can promote blood circulation and avoid sitting or standing for long periods of time. At the same time, pay attention to wearing medical elastic stockings to reduce venous pressure, and if necessary, have regular physical examinations to monitor vascular health, especially for high-risk groups with a family history or long-term bedridden. If suspicious symptoms occur, do not try to deal with it yourself, you should go to the hospital in time for early diagnosis and intervention.
