Good evening and thank you for your question.
Your poor girl, I am glad you have an appointment tomorrow.
The neosporin will be fine, you can also try the warm compress but a cold compress on there may be better.The cold may help to decrease the swelling and make her more comfortable.
To prevent this problem in the future you may want to add a spoon of real pumpkin to her daily diet to increase her fiber and make it easier for her to express the glands when defecating.
I hope this helps make her feel better.
