Hi
I've just noticed your post in the radiotherapy group as I was looking through the list of unanswered posts.
Having had no experience with oedema myself I looked it up on the NHS website where it says, amongst other symptoms, to get in touch with NHS 111 immediately if:
It does say that oedema happens in the ankles, legs and feet so I'm not sure if this is what you have as you say the swelling is on your neck.
I hope that everything's okay.
