I have found another way of uploading pictures and linking them here. This is a test to see if it works. The first I have uploaded was this one, of a plant called comfrey. You crush the leaves and the resulting stuff is a liquid kind of oil. You put it on the limb that has just been plastered or bandaged, and the pain goes away.

One can say this is nonsense but when I had the plaster removed from my arm, it would hurt as it if couldn’t hurt more; I would put this the ointment on, and off the pain went.
