Swollen lymph nodes

[Nanda]

I am Nanda from the Netherlands. 3 years ago I had a long medical traject, because of swollen lymph nodes in my neck, they come and go, some bigger than other ones, but after echo’s, operation they can’t find anything. I have the mirena spiral. In the time between, I was pregnant and those 9 months, my neck was Completely fine, No swollen lymph nodes. 2 months ago it starter again!
I am Reading the Dutch book: “grip op je cyclus”. There are so many things I read that are maybe options that can help me. But I don’t know where to start!
Do You have experience with swollen lymph nodes and advice where to start?
