Ok, I was just curious if you guys though I should I be worried about this or not. I'm not really too worried about this, compared to his other issues right now , but I thought I'd get opinions just to make sure. Lucas threw up bile today (yellow/green slimy). He also threw up bile about 4 days ago. Neither had digested food at all, just bile. His eating, drinking, urination, and defecation are normal. His mood isn't great and he's definitely not as active, but I can tell it's because of his spine issues are getting worse. The only reason I was wondering is because of the medication he's on now. He started it about 11 days ago. The medicine is Previcox (firocoxib). ???
