Avi, I was in that situation a couple of weeks ago.
I was unable to get an appointment at our doctors due to them being fully booked The next available appointment I explained to the GP I am seeing regularly whilst I am off sick and he got a Med 5 form with which he was able to backdate my overdue sicknote.
