Hi, I have had the same problem with swollen and painful  lymph nodes in my neck since I had my 1st COVID vaccination in Dec 2020.  I had bloods and an ultrasound scan and they all came back clear.  I also suffer with health anxiety and i was convinced it was something sinister , but my GP told me the lymph nodes were reacting to the vaccine, and I've been back a few times and he always tells me they may never go away.  I've had more COVID vaccines and after a couple of days of having the vaccine they increase in size again.  I hope this helps.

Hi, thank you this does. I think it’s reassuring to know that it’s not just me experiencing these symptoms
