I'm just now reading this thread about poor Bailey. I had a similar experience a few years ago with one of my Whippets. He was diagnosed with a herniated disc and was put on Tramadol, Deramax & Robaxin. He continued to tremble miserably for days and after researching possible side effects of the drug therapy I discovered that Tramadol can indeed cause tremors. I discontinued it and the trembling decreased greatly within hours and stopped shortly thereafter. I discussed this with both the neurologist & his regular vet - neither had seen trembling as a side effect from Tramadol, but I am convinced that it was the cause. A year or so later when symptoms returned I once again tried the Tramadol/Robaxin therapy and he began trembling. This time I immediately discontinued the Tramadol & once again the trembling stopped. Now when he has an occasional flare up I use Robaxin and Metacam with great success. I have used Tramadol without problems on my other Whippets, but just wanted to share with you the possibility that Bailey may be having an adverse reaction to it. Sending prayers & white light for Bailey.
Hugs,
Stef & the silly 7
