When is the best time to go to A&E?

I keep seeing comments around if your asking do you really need to go etc, and whilst it is true in many circumstances it's not always the case.  After being in hospital 5 times last year, 4 of those times had to be admitted via a&e. I knew what was coming, that I would most likely be admitted to a ward and whilst my life wasn't imminently in danger for most of those, the only way into the ward was to be triaged by a&e.  Luckily most of the time my waits were quite short as in an hour or two but this was mostly in the middle of the night or early morning.  I think some of it comes down to the type of area you live, for some the nights may be a lot busier with drunks etc. I had a room overlooking a&e so saw the ambulances come day and night, day time was busier but there was still a steady stream over night.  Turns out the one time my life was in danger I was waiting for some time, without any pain relief despite me asking multiple times, when the consultant saw me in the morning and realised how bad things were things got moving quickly, and was in the operating theatre within hours.
