Partner (63). Lower back / kidney area pain for 3 weeks. GP said 'back pain' & gave painkillers. Got much worse. Yesterday am much worse & couldn't pee. Partner then passed a stone (agony). Immediate relief. Hours later same process begins. 111 said 'wait on A&E as its a Bank Holiday'. Can they scan bladder or kidneys in hospital to see if more stones? Can they zap or treat them?
