Tail Sprain?

Looks like it got stuck somehow. I see a little bruise.
Usually an injury like that can recover on it's own. I don't think she's going to lose it. Just keep an eye on it, give it about a week to get better. If it get's worse go to a vet. You can give her a low dose of Infant Ibuprofen, but if she's not acting like she's in pain I would just give 10mg/kg (can help with the swelling).

Thanks Velo! <3

I'll probably wait to give it to her tonight before bed, so we can all get a good night's sleep. They're enjoying the chicken bones from gumbo atm, haha.

i've had a couple rats sprain there tails, i dont tend to give pain meds unless they show signs of it bothering them as i think a small amount of pain stops them doing anything stupid (like using it too much of flying around like a nutter). One of my guys sprains recovered perfeclty, the other has a perminant slightly bent tail which curls more to one side than the other. It doesnt bother him but he is less steady generally.

It's a very odd colour for a tail to turn. It looks more like the dye from brightly coloured wooden toys. The bit that worrys me though Is the tail looking narrow in the middle, like it goes in. That could be a purely visual affect from the colouring though. How does it feel, is it warm all along and can she use/move it all the way along the length. Also when feeling along the tail does it go in then out our is it a smooth narrowing to the tip
