Local venous pressure pain is a symptom of thrombophlebitis, which is a common clinical condition. It can occur in both men and women, and is more common in young adults. Superficial thrombophlebitis can occur in all parts of the body, usually in the extremities, followed by the chest and abdominal walls, with a few wandering episodes. The clinical features are: sudden onset of redness, burning, pain or pressure along the superficial veins, and the appearance of streaks or hard nodules. After the acute phase, the cords harden and local skin pigmentation occurs. So, how to prevent thrombotic superficial phlebitis causing local venous pressure pain? The following is a brief introduction: 1, proper warmth: as we know, in a warm environment blood vessels will expand, skin color becomes rosy; on the contrary, the skin will look pale. Therefore, in the cold season and in the room with air conditioning to keep warm properly. The cold will make the blood vessels constrict, blood flow is more reduced, and the symptoms become more serious. 2, pay attention to exercise: functional exercise can not only prevent muscle atrophy, but also increase the blood flow in the limb, to promote the opening of the vascular side branches, to maintain the mobility of the limb. However, the exercise of the affected limb should not be too hasty, and the amount of activity should be appropriate, that is, to not cause limb pain. 3, prevent trauma: trauma not only aggravates vascular injury and spasm, but also makes the limb already in a state of ischemia to reduce the resistance to infection, resulting in wounds that do not heal easily. Even mycobacterial infections, such as tinea pedis, which are usually disregarded, can pose a threat to the affected limb; therefore, once trauma or foot mycobacterial infections occur, they should be treated promptly. 4, reduce blood viscosity: blood flow is slow and blood viscosity increases, which can cause thrombosis and complete blockage of the originally narrowed arteries. Therefore, you can also usually by drinking more water.
