Hi, I've had a sore throat and loss of voice for a week now, this morning I woke up with cold like symptoms ie sneezing, dry cough, blocked runny nose. As the day has gone on I have developed blurred vision, lethargy and breathlessness. I have also suffered with painful headaches for over 2 months now which I put down to stress but have worsened with other symptoms. I have no appetite, and abdominal pain. Over the counter medicines are not working. I cant warm my body inside even after having hot drinks.
