That makes very good sense. I don't hang upside down completely, but when off, with dystonia [also brought on by just being off first thing in the morning especially, or by movement or straining on the neck and shoulders, now joined by a damaged lower vertebrae and life can be limiting to say the least.

I put my head, top down, on the floor, and bring my arms back ro my sides, body hunched up, knees underneath, sitting on my feet, stretching, seems to get some blood to the upper extremities and head; then do the yoga dog stretch; or I lay across the bed, stomach down, with shoulders, arms and head hanging over the edge. Finally lay on back with legs sharply elevated. It helps after awhile - not immediately. All involve blood circulation, stretching, getting on.

It's a must or freeze right up in total pain. Drug addiction involved too, I'm sure....since we take a few...lol.
