oh, my idiot doctor put me on simvastatin a whiel ago. After a few months I started to get aching arms, so went back and a locum said "Oh, it'll be the statins, I'll take you off them." When she looked back through my record there was no reason I should have been on them the first place and all subsequent blood tests say there's nowt wrong with my cholesterol.
There are a variety of them and one might work where others don't.
That was a different doctor from the one I went to with a pain in my ribs, Robi... he poked around and told me I had intracostal neuralgia, which is a pain in the ribs but in Latin, so that shows the value of education..
