Pet rat foot injury - Should she see a vet?

hello! there's a few things you can do. if there's an open sore on her paw dip it in honey, honey has awesome healing properties that works wonders on my rats and it's safe if they lick at it. if it's just swallen looking alternate warm compressions with cool compressions every 2-3 hours for 15 mins at a time since your baby doesn't like being held much wrap her in a towel before you do it to keep her from escaping. another thing you can do if she's acting like she's stil in pain even if not squeaking (remember Bruxing is also a sign of discomfort) give her a dose of infant tylenol (1/2 way up to the very first line on the dropper) you can give this to her every 6-8 hours. honestly though it's going to take about 4 days till she puts any pressure on her paw and a total of a week till she's walking normally. honestly you should have no reason to go to the vet. just keep her in a small cage so she doesn't have to move around to much for her food and water, give her tons of rags and soft fabrics/bedding for her to snuggle into and give her 3 rounds of free play a day for a max of 15 mins just to encourage her to stretch her injured paw and attempt to use it or just let her camp out on your lap for a nice 45 mins to an hour at a time.
