Supraclavicular swollen lymph node 10 months after Covid jab

Hi. 
 

I have a swollen virchows node. It first appeared  swollen in April 21 following my Covid vaccine. I had blood tests and an ultrasound and was told it was swollen but nothing to worry about. I tried to forget about it and accept it may always be swollen but it is still there and I have started to worry again. Sometimes it sort of aches. Can't help worry that something has been missed. Has anyone else still got swollen lymph nodes following jab last year xxxxx
