she was ill all last week at work and finally went to a walk in centre today and was told that what she has. She is insisting she will be in work tomorrow !!
I don't want to scare you but I was very ill when I had pleurisy and it turned into pneumonia and I ended up in hospital! I'm not saying this will happen to your friend but it is a very nasty infection and she should get plenty of rest and visit her doctor.
She should stay at home really. I had pleurisy which turned into pneumonia - I only took two days off work which is probably why my illness lasted five months. My lungs are knackered now. Every time I get a cold, I end up with a chest infection. Tell her to rest up and get rid of it.x
As long as her work is not labouring and is basically office work and as long as she doesn't have a temperature or coughing up phlegm, then if she takes an Ibuprofen to ease the chest pain, she should be fine to go to work.
Go to work and just monitor the situation, or if you want an excuse not to go to work...............then don't go.
