Need help and advice!

[Valvaren]

So I just took my female brazilian out for a little handling time and notice something wrong, she has a lump on her head, I don't have pictures atm since my fiancee is not home to help me hold her and get some.

I just fed her sunday night and she ate no problem, she has never missed a meal not even while in shed. She is roughly 8 months old, Her humidity is 95-99% and her hot spot shifts between 79-82. Her temps are measure by a hydrofarm thermostat and a PE2 temp gun.

As stated shes never missed and meal and has shown no signs of having any issues. The lump is just between her eyes and has had no signs of pain when its bumped or anything. She has shown no aggression or defensiveness other the her normal behaviour which is just defensive before being picked up.

I'm not quite sure when is first formed since I fed her sunday I don't handle them a few days prior or after. She is fed F/T pinks and I watch her eat and she sustained no bumps or anything.

I don't have a vet around my area that I trust with these little gems, I want to get a feel of what I am looking at before I risk taking them to someone who will more then likely cause more harm then good. I say this because most of the vets in my area I have talked to do not know the difference between and iguana and a BD. I'll get calling around and looking for someone to take her to but I want to know what questions to ask and what information to go in with regarding what it could be before I just walk in somewhere.

I will try to get pictures tonight, is there anything in the husbandry I should change to possibly help?
