At the start of the week I had a ticklely cough that I put down to an increase of my Lisinopril from 2.5mg to 5mg (ACE Inhibitors are well known for causing a dry cough although it often settles in a few days). However, on Thursday I woke with a red raw sore throat, and streaming nose and eyes. This stayed much the same during the day but worsened with a near constant cough as evening approached. I had an awful night. Observations the next morning showed a slight rise in BP, my usual pulse of 55 - 60 at 77, a slight fever and my O2 down. Anyway it was decided to call the GP and I had a telephone consultation. He thinks it's 50/50 I have Covid! All I know is I feel absolute rubbish. I have had a PCR test and am waiting for the text that says yay or nay. Meanwhile I am isolating, coughing and sleeping. Absolutely zero energy!
