Ds has recently been complaining of intermittent pains in his knee joints. First it was just the one knee and I thought he might has twisted it, though no evident sign of swelling or bruising. He complains in the morning and also when he's playing on a bouncy hopper. I thought it might be growing pains but its the wrong side of his knee and its not at night. If I take him to the GP will I get put down as a fussy mother - I rarely if ever go normally - or is this sometihng I should be worried about?
