Phlebitis can be cured, but it can come back if not treated aggressively. Phlebitis heals better and patients with mild symptoms usually resolve on their own in 3 to 4 weeks. If deep vein thrombophlebitis occurs, the duration of the disease is much longer, and the symptoms can be relieved by anticoagulant treatment for 3 to 6 months. If left untreated, phlebitis is at risk of recurrence. Depending on the type of the disease, phlebitis can be treated in different ways, including antibiotic treatment, physiotherapy, symptomatic treatment for pain relief, anticoagulation, surgery, etc., and it is necessary to choose the appropriate treatment according to the patient’s condition. When phlebitis occurs, it is recommended that the patient go to the general surgery or vascular surgery department in a timely manner and follow the doctor’s instructions for standardized treatment to avoid the progression of the disease, which may affect the patient’s prognosis.
