Lymph nodes, CT scans and Mammograms
It is reasonably common to have swollen lymph nodes (commonly called ‘glands’), especially near the vaccination site eg under arm or in neck, after vaccination. It is one of the top 10 potential responses seen after COVID-19 vaccination, and occurs more commonly after booster doses than earlier doses. This is part of the normal immune response to vaccines and infections.
If you are having a CT scan or mammogram in the near future and have had the vaccination, or you are planning to have it, let your health professional know as it is possible you may need to reschedule.
