I started feeling tired all last week and thought maybe it was as a result of starting taking my antihistamines (cetirizine). Come Saturday I felt quite ill as in very tired, slightly nauseous and headachey but what concerned me most was that my feet and hands became puffy/swollen. They did not really ache just felt a bit tight. I could not get any shoes on other than my flip flops. I went to the walk in centre and they checked me over and said they thought it was a virus but to see doctor on Tuesday (after bank holiday). By Tuesday I had developed a non productive cough which was much worse at night - could go a lot of the day without coughing apart from a few outbursts which were intense and breathtaking. Went to doctors on Tuesday and she said virus, just take ibuprofen. Since then I have had a rash and pain confined to my knee which lasted about 8 hours and has now moved to my elbow. My knee feels ok again and although the rash covers the outside of my elbow it is not necessarily painful but feels hot. I suspect this will move too. I go through periods of feeling a bit better and do a bit of work but then I feel overwhelmingly sleepy. I also have an ongoing headache and aversion to bright light as well as some slight itchiness of my skin. Has anyone else had a virus which presented itself like this? How long did it last? I have never had anything like this before and I am worried it is something more sinister.
