So glad to hear that - it must be a big relief! 
Mine is slowly reducing so I am feeling more relaxed now. Thanks for keeping us updated

I think the nodes go down much quicker with some people

Mine is definitely smaller now too.

I thought it would flush in one go sort of thing but it seems that it's going to slowly go down.

I have been finding these posts really helpful and so I thought I would post my experience too. I had the AstraZeneca vaccine on the 1st April in my left arm. On the 9th April I discovered I had a swollen lymph node nestled next to my left collarbone. It was about 1.5cm, mobile and softish. I don’t know how I discovered it because it is not an area I thought I touched very much. I also don’t know how long it had been there for. I went to see my GP on the 26th April. The lump hadn’t changed in size at that point. She arranged a blood test and told me to wait another couple of weeks to see if it shrinks, before coming back. During that wait, the lump began to diminish in size but it is a very slow process. I saw the GP again on the 10 May and she was pleased that it had gone down in size by about half. The lump is still mobile and soft. My blood was all fine. She has told me to come back again if the lump doesn’t keep diminishing but seemed happy that it is more than likely due to the vaccine. I do feel relieved that it is getting smaller but it is taking a long time.

It does seem to take different amounts of time for different people. Mine is slowly getting smaller. Two weeks since it first appeared. 

I'm so glad I've found these posts. I had my 2nd Pfizer jab Friday 30th April. The next day my collarbone felt tender left side and then I felt a lump near my collarbone. It moves when pressed and I can only feel it in certain positions. Called the GP last week who never mentioned could be caused by the vaccine and really frightened me. When I then asked if could be vaccine he said um possibly but call back if still there end of this week to arrange bloods. I'm so terrified. 

Actually my swollen right node seems as big as ever after 7 weeks, but the ultrasound man said 'no further action'  – unless it gets bigger. My second vaccination is on 22nd May. We'll see whether another node comes up or not....Hope the first one doesn't get bigger!

This sounds like the same thing that I and other people here have experienced. Bloods and ultrasound were OK for me and others, so try not to be worried, and think of other things as much as you can. I think it is becoming known as quite a common vaccine reaction

3 weeks in no change in lump for me. Still mobile, firmer than tissue round it & smooth. Its basically like a small butter bean. Not visible unless feel for it. Left lower neck.

Had bloods done & fine. Referred for ultrasound as routine as lump under 2cm.

Thinking about paying private if referral comes with silly wait time.
