Before I am asked if everything is right, it is. Her tank is the right temps, she has all of the right lights and she is given vitamins, calcium and has the best uvb money can buy. She had an episode two months ago where she couldn't use her whole left side, she was dragging it. After one day it went away and I never thought of it again. For the last coupe of weeks she has been shaking her head like in the video, but it is becoming more noticeable. I am going to get her into a vet ASAP but they are closed today- please help me with ideas of what it could be.
