I've been stunned this past couple of month at just how pants the NHS are. To get an appointment at my doctor's surgery you have to call at 8.30am, and can never get through, I needed to go just before tour and I had to be stood at the surgery doors at 8.29 to make sure I could speak to someone.
Needed to go back a couple of weeks ago as I needed some anibiotics and waiting was just not an option ( I shall spare you the details
) and she offered me an appointment for almost a week and a half later, it's terrible...
Hope your tooth feels better, I've got two wisdom teeth coming through at the minute so I truly sympathise!
