I think I've had it for quite a while but I've only really noticed it as it's large. It's a hard lump on the right, centre of my neck. It's about 2inchs all the way round and you can see from just looking. I haven't had a cold/sore throat recently at all and I can't feel one coming. There aren't any other symptoms and it doesn't hurt. Just confused, I think it's a gland but I don't know why it is swollen.
