Ok, I think I've just strained it /set off achey back by wearing heels instead of flatties, but I've had a painful warm-feeling calf for a couple of days. There is no redness or swelling at all (I keep looking!).
The right hand side of my lower back is a bit achey, as is the right hand side of my foot, which is a bit crampy - wondering if it sounds like sciatica?
Don't want to bother the gp unnecessarily, so hoping stretching, anti-inflammatories, rest will do the trick (wine?). Have convinced myself that my leg will explode or something dramatic - slap me with a kipper please oh wise mners.
