Hi Na-41.

Swollen lymph nodes is a known side-effect of the Covid jab, and it seems that a number of breast clinics are finding patients with swollen nodes, so you're not alone.

Under normal circumstances, when lymph nodes are reacting to an infection, they usually subside and settle down within 4 weeks, and most doctors suggest you should see your GP if they haven't settled after 6 weeks.  This means the advice you've been given to wait 4 weeks before seeing your GP makes perfect sense.

I know how difficult it is not to worry, but a quick search shows that there are a lot of women in a similar position to you after their Covid jabs.  I guess it's what happens when they roll out a vaccine to millions of people in a short time.  Put a cross on the calendar for four weeks time, and put this out of your mind until that time is up.  Then check for the nodes and I expect they'll be gone.

Meanwhile I have my second Covid jab in two weeks time....
