If goats can fly that does explain a lot of escapes! There have been many times that I've found them where they're not supposed to be and it can be a brain twisting exercise trying to figure out how they got there. Flying makes way more sense.
The cold/flu thing is over now but the leg is still causing a lot of trouble. I'm hoping the arnica does the trick soon.
Hahaha! Flying goats! Indeed you have hybrid goats with hidden DNA that can shift gravity for them!
Have you tried putting your leg in a pale of warm water?! Or you could put warm cloth over your injured leg, this will help with the swelling and loosen the tensed muscles!
Good luck and get well soon!
