Thanks for the responses ladies!! I had the HCN check it today at MG... basically it is in her lymph gland and its completely normal..yay! She said they usually get them when they are sick (Izzy hasnt been though) and thye stay for a while. She also said it may move and we might find it has moved to a different place! So *sigh* its not serious and Im very relieved!
Leanne30 - HtHs - although if you are worried you might find it a relief to get your HCN or GP check it out!
