Well, I think we've actually exhaled now, after a couple of days of uncertainty and concern. Boomie has been having some trouble. Weakness? Pain? It was hard to figure out exactly what was going on, but he was unsteady on his hind leg and walked with a slow, somewhat hunched posture. I started him yesterday on Tramadol from the sizeable stash we have left over from his amputation. (Yes it's still within the "use by.." date.)
This morning he seems to be considerably better, but I still don't know what was wrong in the first place. Did he sprain something? Has the cancer returned? Is that poor old arthritic, displastic back leg wearing out? I will keep him on the Tramadol for a few more days, and then wean him off of it and see what happens.
