Lump on Tokay Gecko?

[Gatorqueen]

I just got a new tokay gecko about a week ago from my local repticon (all I know is she's a female wild caught tokay and they had already been treating her for worms) and she looked fine when I got her but suddenly she's developed a a large lump on her neck and I have no idea what it is. She seems fairly active, but she has not eaten since I've had her, even though I've been offering her superworms and dubias. I also haven't handled her so I have no idea if its firm or soft. Does anyone know what's might be going on with her?

Is the lump soft and squishy or hard? It sounds to me that it's worth a vet visit.
