am 14 years old and I have had this lump on the right side of my neck. I have had it for 6days now. It is quite big or even meduim sized, but it hasnt decreased or increased in size. It is hard and unmovable and i dont have anything else apart from a sore throat that only comes when I wake in the morning. On the second day i got it i went to A&E and they said i have a swollen lymth node that has been there more than a couple days and that it could be TB or inside growing tumor and that i might need a biopasy. But he also said i could be just an infection.He gave me some antibiotics and told me to tell my GP for further investigation. So the next day I did and my GP said it is just mumps and gave my paracetamol. Now i have two different verdicts so I am just worried of the unknown I just don't know what it is! any ideas?1
