Dog's Tail isnt looking good

[SoggyRedNeck]

She woke me up about 2am the other night whining and crying i couldnt figure out what it was until i picked her up to put her on my bed and touched her tail. She finally just went to sleep but the next morning her tail was swollen and limp. 2 days later its still swollen at the base and just kind of hangs there. When she gets excited it will stand up and wag but only when i get her extremely wired up. She can feel all the way down it so its not numb, just swollen and limp. It hurts her for sure bc when you try and touch it she tucks it but doesnt hurt bad enough to where she will scream when you grab it.

Any ideas? If someone can shed some advice that would keep me out of the vet's expensive company it would be much appreciated, but if it aint better by tomorrow ima bite the bullet and bring her.
