worried

I hate this.

Dave had a good night, with no vomiting or diarrhea. However, we noticed that he's having issues walking. He used to do this little kick out thing because he had a nail that would fall out all the time, and it was sensitive. Now he's alternating doing it with both legs, especially when he is outside. He spent a lot of the night before going to sleep and this morning licking his paws. I examined them, and didn't see any signs of trauma. He chose to jump into bed and onto a chair, so it seems like more of a sensitivity issue rather than his legs not working. I'm going to leave a message for the vet this morning. I'm wondering if it is an allergic reaction that's finally coming out, as the paperwork says to look for paw swelling. I don't think that his paws are swollen, since they look about the same as the front ones, and none of them look overly puffy or inflamed.

Oh, and we did give him the benadryl last night as a precaution. I'm trying to balance my reaction. I feel like I've always overreact about his medical problems in the past, but now I'm concerned because I feel like I'm underreacting. Bleh.

**UPDATE**
The vet called me back already (8 am), which makes me feel a little better. She said that she doesn't know what the leg problem could be, as it would be unusual for a patella or hip problem to just appear with no prior signs. She advised to continue the benadryl, also. She said that we could bring him in to Penn, but that taking him tonight to his scheduled appointment would be fine as well. She said that because he's eating and the vomiting has stopped, and he's relatively bright and alert, that she's not overly concerned. She reiterated that reactions to Elspar are very unusual, but that's not to say it's not possible. This is his last dose of Elspar for the cycle, so there aren't future risks. She said that hopefully by the end of the day and tomorrow, that we'll see these symptoms going away. Hopefully...
