this sounds incredibly feeble but 4y0 ds fell over earlier today at CM's and has what looks like tiny tiny bit of grit stuck in cut. can't get at it with a needle or tweezers and after half an hour of trying he is now hysterical. DH, who is not one to under-react, phoned NHS direct who said take him to A and E but not sure this really merits spending four hours among the assorted drunks. any advice?
