OK - so here's the latest.
I had to run in town this a.m., and noticed a light on in the vet's office, so thought I'd stop in and make an appointment for Monday. When I told her what was going on, she said to bring him right in - today! Came back home to pick him up - and of course he wasn't limping again after being hardly able to walk all day yesterday and this morning! :eek:
The first thing I jokingly asked her was if they are capable of playing head games - and she gave me an emphatic "Oh yes!!!"
So we went in, and the first thing she suspected was Lyme's (typical symptoms) - vaccines are only 80% effective. She drew blood for a test and it came up negative. She doesn't feel it's arthritis since it came on so sudden, so it's probably looking like a sprain or jamming type injury. It might feel better for a while and then he somehow aggravates it by jumping up and down off the bed, or going up and down steps. She did say too, that she saw a hint of a limp, but it was nothing compared to what it has been.
So - I have to lift him up and down off the bed, and carry him up and down the steps for a couple of weeks - a baby aspirin 4 times a day - and if he hasn't drastically improved in that time, then she will do an x-ray to check for arthritis.
So at least that has relieved my mind somewhat. If it's just a sprain, then that's great - if it's arthritis, at least he can take meds for it and it isn't life threatening. He and I will just hobble along together.
Sparky and I both thank you all for the prayers and positive vibes. :love:
