Googling equine diseases online is just as bad as webMD.
So after I pulled myself out of that downward spiral of sialoliths and tooth extractions...
|"I'm ready for my close-up, the lighting is magical"|
My vet consulted with a surgeon colleague and they didn't see anything abnormal or suspicious in Tesla's teeth/jaw x-ray (Yay!). They did notice her lymph nodes were slightly swollen, and prescribed a round of antibiotics. In the last few days the tenderness has disappeared (as well as the head-shying) whether it was the antibiotics, or it was resolving on it's own, either way I'm relieved!
Thanks to everyone for all the well wishes, mystery ailments are the WORST.
