I hope it turns out to be nothing. Good luck.
clysta- that is what i thought when she was younger probably why i totally brushed it off and forgot about it.. (i feel terrible but that part of her neck isn't somewhere i often feel):( joyrenee- thank you i will do that.
A lump that has grown in size is something to be concerned about. I wouldn't wait 4 weeks. I would call first thing in the morning and see a specialist.
If I remember you have lymph nodes in your neck that can become swollen and stick out. I had them in the back of my neck when I got mono. My sister also had them, but she had ALL. (don't mean to worry you) Call your doctor and ask them what they want you to do. They might want to check it out to see if everything is ok. I believe they can also become swollen when you're sick as well.
