Just make sure the tub/tank humidity is staying constant at around 50-60% and she has access to clean water, eats healthy prey that is well fed and well hydrated itself and I'm sure she'll be fine. Likely she's in poor condition due to the injury and stress. Once she's healed and has shed a couple of times she'll likely look fine again.

Just make sure you aren't oversoaking her. Sort of like when you sit in a bathtub for hours and you end up dried out, snakes can also lose moisture from being soaked too often or for too long a period.
