HELP! SAND BOA NOT EATING

Ya, it could barely walk so I didnt see any threat from leaving it in. I want to get her fattened back up nicely again before I go about trying to get her to eat by different means. Id really like to wean her onto frozen for the sake of having to drive across town for live food on a weekly basis...
 
I hope it doesn't come down to force feeding because pinkie pumps are the grossest thing I have ever had to use. Gives me the shivers just thinking about it...
