I have had a large swollen, painful lymph node in my neck for a couple of weeks and a smaller one for a bit longer. I was thinking it was an inner ear infection but I have had no ear pain. I've had no other infection symptoms either. Spoke to the doctor today who is sending me fir bloods and an X-ray. He feels it's unlikely to be an ear infection. Obviously now worried but I think the node has gone down a little. If it was blood cancer do lymph nodes swell and then go down or are they permanently swollen?
