I might err on the side of caution and have the vet at least palpate the tail for soft tissue damage, and examine the tail on radiographs for abnormalities along the coccygeal (tail) vertebrae for fractures, disc ruptures, etc... They can also prescribe some anti-inflammatories for pain which will provide immediate relief, and if necessary, bandage it to prevent further injury and reduce risk of bony changes.

But you know your chi better than us, so if you think your chi needs medical attention, I'm sure you'll pursue it! Good luck and get well soon! -Nate
