My right shoulder hurts. It has been hurting for a while, like a few months, or maybe a couple of years, or – now that I think about it – perhaps a decade, on and off. I don’t recall injuring it, so I am not exactly sure what is causing the pain, although it’s quite possible that the gazillion times each day I lift things and reach for things and hand out things could be a factor. Parents like myself may be aware that one particular move alone – driving with the left hand while handing items to children in the back seat of the car with the right, repeated daily over years – could cause serious shoulder complications. I have not been able to pay much attention to the pain over all this time,
