savannah monitor not eating, suspected impaction

[ecbee]

i own a roughly 3 year old savannah monitor who came from a womans house who did not know how to properly care for a savannah monitor. she was housed on decorative fish rocks and wood chips which i quickly changed to 1/2 top soil 1/2 play sand and corrected the humidity and the temperatures when she came into my care. within the first month of her being in my care she passed 3-4 decorative fish rocks from being in this womans care....
ive had her for a good handful of months but since she wasn't raised correctly on the right diet she is not apt to eating insects unfortunately but she doesn't mind rats at all. we've been feeding her weaned rats i believe thats the size she is eating with a mixture of trying to feed her some meal worms when she will take them and horn worms. she gets the occasional egg but only as a treat.
my problem is.... she WILL NOT eat. ive tried giving her anything and everything...
smelt, quail eggs, rats, mice, african soft fur rats, hornworms, meal worms, crickets ... everything. the last thing im going to try are some roaches. what im thinking is she might be impacted.
ive tried warm baths while massaging, i increased the temps, monitored the humidity and still nothing. yes vet care i get it if a couple more baths dont do the trick she will be going there this upcoming week, just creating this post to try and get some feed back
anyone out there able to help me?
