The RR and vanilla sound like a good idea.

Even though you moved two months ago, he might have smelled something "new" .

Does he dislike his harness?

And your poor back! I know you are likely getting "helpful" advice from many people, but deep-sea Omega 3's(for pain) and Dong Quai(relaxant) can be very helpful

If you get it, go to a health store or elsewhere. If the stuff has a DIN number on it, then you know what is on the label is in the bottle! (Non-DIN stuff can say, for example, 500mg on the label - and have 200 - 1000 in the actual stuff!)

I REALLY hope you can heal up soon - and that the docs can figure something out! HUGS!
