Hi David
As for me I had a spell of nearly a week in bed with flu 🙁 and to top that off I then got a chest Infection so took a trip to Dr's and he gave me some Anti Biotics and a sick note for a week:-/ when I told him i dint want to be off another week he said "Where were you last week?" and i said I told you I was in bed with Flu? to which he replied "and you turn up to see me on a friday I give you anti Biotics and trust me he said i dont give these out freely so take these and ONE week on sick and you will be OK" and do you what he was correct Lol, so its back to work on Monday Bug Free, so my advice would be nip and see the Dr and get something strong to knock it off.
Good Health
