The doctor we went to see said that the shingles are probably an indicator that there is something else wrong with Spindles. We will investigate that but possibly with a different doctor. He was very ancient, and kept us there in silence for quite a while before speaking to us, then when he did attend to us he seemed surprised at first, as if he had forgotten we were there!
He was very surprised that Spindles actually did have Shingles (I told him of my suspicions before he examined Spindles), as it is really an adult illness. Thankfully it is a mild case. And I have a slave for a week! Hehehe.
