Can occur in arm on side of lymph node removal and mastectomy?

After lymph node removal and mastectomy, one may experience lymphedema, a condition characterized by swelling in the arm on the affected side. This occurs due to the disruption of normal lymphatic drainage, leading to a buildup of lymph fluid. Symptoms can include swelling, discomfort, and a feeling of heaviness in the arm. It's important to manage this condition through physical therapy, compression garments, and other interventions to minimize its impact.
