I'm an utter amateur at this and have never called them before, so genuinely have no idea. I guess it's a question of how busy they are / how serious I'm deemed to be?
I spoke to them at 7pm and still haven't heard. I have absolutely raging toothache which has developed from a bout of (possibly) neuralgia. I haven't slept properly for a couple of days (was ill prior to this) and genuinely feel I could murder someone - uncharacteristically for me I even had a little weep earlier. I've missed three days work so far and there's no way I can go in today unless I can be furnished with some stonking painkillers
