Thrombophlebitis lumps are mostly due to an inflammatory response that develops when a blood clot develops within the blood vessels of a vein and further irritates the blood vessel. Thrombophlebitis is a sterile inflammatory condition that occurs within the blood vessels. The disease is most often caused by damage to the walls of the blood vessels, hypercoagulability of the blood, slow blood flow and other factors that lead to the formation of blood clots in the blood vessels, which in turn further stimulate the blood vessels to form lumps. It often manifests itself in symptoms such as lumps and pain in the limbs. Clinical treatment of thrombophlebitis is based on prevention, mainly through the use of bed rest, hot compresses, compression stockings and other ways of symptomatic treatment. It is recommended that if you have any discomfort, you should go to the hospital in time to clarify the cause of the disease and choose the appropriate treatment program under the guidance of the doctor.
