After the administration of the Covid-19 vaccine a number of side effects have emerged, among them, the swollen or tender lymph nodes under the arm. Faced with this symptom, a group of radiologists from the Massachusetts General Hospital (MGH), who conducted an approach to monitor these occurrences in women who have mammograms to detect breast cancer, note that this reaction is “normal” and that it generally disappears with time. However, they have expanded its recommendations to include the care of patients undergoing further tests after vaccination.
