Have a speedy recovery Marc, take plenty of rest, Don't go back to work until your doctor says your fit too,
Many years ago my doctor signed me off sick for a week with a bad Chest infection, my Boss at the time pressured me
to come back to work early after been off for just 3 days, which i stupidly agreed too, then after a couple of days back
to work my condition deteriorated a lot worse then it originally was, long story short i ended up having over a month
off work before i fully recovered.
Best regards
Lal
