Hi Charlie 

If she has said they are reactive then she thinks an infection or virus is causing the nodes to swell. She has given the antibiotics to see if this will reduce the swelling and it should. If not she will probably organise an ENT appointment to have further tests such as an ultrasound, biopsy and a camera to have a look around your throat/nasal passage.

Try not to worry as this is normal procedure. I also had a swollen node that I had an ultrasound on and it came back as normal and not for concern, I was told it may never go back down to it's normal size!

All the best

Patrick

Thank you very much :)
