Our expert says:
A reactive lymph node is usually due to inflammation after infection or part of active infection. You can ask your GP for an ultrasound of the lymph node to investigate if there is active infection with a collection of fluid. A fine needle biopsy would be the best investigation. A fine needle is inserted into the lymph node and cells are drawn up for a histological diagnosis. In the case where the lymph node is surgically removed, there can be severe swelling of the arm.
