Cali, you do realize that the more often you get concussions, the more likely it is to create long-term problems, right?

IME, they don't CT scan every head injury who walks in the door, but if they are exhibiting symptoms such as dizziness, nausea, memory loss, they will almost always do a CT of the brain to rule out a hematoma or bleed.

The fact that you took the word of a VET not to go to the doctor makes me want to beat the vet upside the head. A VET IS NOT A MEDICAL PROFESSIONAL!!!!!!!!!!!!!!!!!!!!!!!! A vet does not have the training or knowledge of human anatomy/physiology/medicine to tell you that you are "OK". For fuck's sake. There's a reason they can do a colic surgery, but can't walk into the OR of any hospital and fix a perforated bowel. GO TO A DOCTOR.
