now should I worry, my best friend has a bad cold, she is diabetic, so ... we have both had both jabs... she is early 50`s, I am in my 80`s, but overall I am in better health than she is, (so far as I know.) docs don`t want to see us do they! so I can`t get checked for health conditions
You can use the free Lateral Flow Tests to test if you have Covid. They're not perfect, but might pick up infection.
If your friend's cold persists, she should really be tested for blood glucose levels, which can rise quite dramatically in diabetics when they have any kind of infection. If she has a home monitoring device and test strips, she should use it. If she has persistent high blood glucose, she should contact the GP for advice. If she's not already taking insulin, she might need some until her blood glucose returns to normal (for her).
