Yes, here in BE the nasal spray was taken off the market because of a higher "risk" of cancer occurring. The injections are still widely approved and are okay to use. Because the administration is different.

The brand you can get over here is called "Miacalcic".

I have to say it works well on my arms/hands. I was getting a cold right hand, and with extended use, the cold dropped from shoulder, to an elbow, then from my elbow to my wrist and then the fingers, and now my arms are basically doing fine, but not stable unfortunately.

And it no longer does anything (in the sense of mobility) for my legs. It does keep them a higher temperature (less cold). So that helps hugely.
