I had a sore throat but felt well in myself for most of last week. Christmas Day I felt dreadful. Aching, nausea, exhausted. Don't remember ever feeling this ill with a cold. Since then it's been getting worse. I still ache but now my sore throat is agony and I have a cough that's ripping me apart and feels like I'm drowning. Three days of feeling awful with no improvement.
How much longer?
