My adult son has lumps in his testicles, severe abdominal pain and sickness and a low temperature of 35. He's been feeling very ill for several months now. His GP has done blood tests which show a low white blood cell count, anaemia and low thyroid. He phoned them this morning to make an appointment due to worsening symptoms and the receptionist said he couldn't have an appointment as his blood tests were 'ok' and there was nothing more to be done. Where do we go from here? He's in London. I'm tempted to pay for him to have a private investigation as he's got nowhere with the NHS, but who with? What sort of specialist is needed? He doesn't want to go to A and E as the receptionist made him feel like a time-waster, but maybe he should. All suggestions gratefully received.
