Yes, I've developed shingles. I don't know why, and all my reading (for example) has not explained to me how or why you get it. It seems to appear spontaneously in certain individuals, and more than 1 in 3 people develop it, usually as they get older (60 and over). You have to have had chicken pox earlier in life to be at risk.
My shoulder is really hurting this morning, so I will be brief. I think our current heat wave is affecting me more than it would if I didn't have this severe shoulder and neck pain. I'm moving about as fast as the creature in the photo above — a big red slug, longer and fatter than my index finger, and one of many that we see around the edges of the vineyard year-round.
