I'm 15f and I'm summer 2018(I think) I found a lump under my ear and next to the corner of my jaw, it feels hard but not like bone hard and it moves a bit . I showed my mum and she said it was probably just a swollen lymph node. I can't remember if I had a cold or anything before it came up because I have a strong immune system and when I get colds they are never really that significant. Because my mum said it was probably fine I brushed it off. Later on like a year later I told my mum that it's still there and never went down, she decided to take me to the doctor and they just said it was a reactive lymph node and it was fine. So as I was like 12-13 I brushed it off and forgot about it . One day I remembered it and decided to look online to see if it was normal but everything was telling me I have lymphoma. I have no other symptoms at all but I've read that people can go for years without symptoms and I don't think the lump has grown or anything but I also read that with some types of lymphoma it grows slowly so I could just not be noticing it. I'm really scared and have not been able to sleep for the past two nights over this I've asked my mum to book me another doctors appointment so I hope to get answers soon. I'm just her to ask if anyone has a similar situation or advice. Also I thought I'd mention that I have had swollen glands before after I've had colds wich have just gone down. (Also sorry if this makes no sense I'm not very good at English)
