I have seen animals refusing everything and taking reptilinks. Now keep in mind that if you offer that often (everyday) she will definitely not make progress, doing so you basically are stressing her even more.
Vet have little to NO hand on with snakes when it comes to feeding habits and will usually start talking about X-ray, blood test etc. They merely have experience with larger snakes, with that species and that size it is not likely that you will find someone with any knowledge at all.
It's possible they can get startled very easily remember she is very small it does not take much.
