What makes under arm lyumpnodes drain after surgery?

After surgery, particularly for breast procedures, underarm lymph nodes may drain due to the disruption of normal lymphatic flow. Surgical removal or alteration of nearby tissues can lead to an accumulation of lymph fluid in the area, causing swelling and the need for drainage. Additionally, the body’s inflammatory response to surgery can increase lymph production, further contributing to drainage. Proper management post-surgery, including physical therapy or compression garments, can help facilitate lymph drainage and reduce swelling.
