On Thursday I took ill with a fever, stiff neck

Patient: On Thursday I took ill with a fever, stiff neck sickness and diarrhoea and by Friday it had got worse so I went to the doctors which she told me I had a viral it’s now Sunday and I still got the diarrhoea and keep feeling faint. My stiff neck is still quite bad I was wondering is it just a viral or do I need to go back

Doctor:
