Phlebectomy is generally a safe and effective procedure, but it may have some side effects. Commonly, patients experience mild bruising and swelling around the incision sites, which typically subsides within a few weeks. There may also be some temporary pain or discomfort, easily managed with over-the-counter pain relief. Numbness or tingling can occur if small nerves near the veins are affected, though this is usually temporary. Small scars may form at the incision sites, but they tend to fade over time. In rare cases, more serious side effects like infections or superficial blood clots (thrombophlebitis) can occur, but these are uncommon with proper aftercare.
