Im an A&E nurse and pressures are higher now than they ever were even in covid. Waiting hours and hours in waiting rooms is sadly the norm these days and completely unavoidable.
However, you 100% should have been offered a change of clothes and facilities to clean yourself up a bit and assistance if needed. As well as the standard gowns, my dept has a store room full of donated clothing for patient who dont have suitable clothing to return home in. It is very well stocked with generous donations from the community. Please, please complain about this as that needs to change in your local department.
Awaiting a consultant to make a decision is also the norm - as in your case a consultant w3ould need to review those scans before you left. An A&E dr would not be able to read and give a diagnosis like that, it would have to be neurology, so neurology would have to site the scan. Only neurology would have their own ward of patients, own surgeries, own clinics and out patients, so waiting for them to make a decision on whether they can fit you in there and then is the only way. Nights often only 1 neurology dr would be on call to cover the wards and emergencies. So frustrating for you as the patient, i fully understand, but A&E staff couldnt do anything other than wait either in that situation.
As far as the post asking why it takes so long, its not just down to drs in A&E, its flow throughout the entire hospitals. Dr's need a private area to see a patient when they walk in (so only considering walk in patients) this area generally known as ambulatory, if a decision to admit is made, they need somewhere within A&E to wait until a bed is available for them, this is the Majors, they then leave majors to go to a ward. If wards cant discharge, theres no flow through majors, which holds up ambulatory. Even if the person in ambulatory is waiting for a minor injury they could go home with after treatment, that cubicle is needed. And its all good saying, well keep some open just for minor injuries, that is tried, then you have an influx of patients requiring immediate treatments and the rooms have to be used and the minor injuries are left waiting.
A&E department waits arent just down to an increase in visitors to the department, but flow throughout the entire hospital, alot of which is held up by social care - or the lack there of, and many many other complex factors.
But please do not think its just staff not working hard enough, A&E is the hardest job ive had in my life, its the only place ive worked as a nurse where i have truly had no choice but to miss breaks, to work 14 hours with no break and have to be back on shift 10 hours later and do it all again, to go home and cry because i know i havent done enough for all my patients because 1 patient was so acutely poorly but the was no where to move them too and my other 6 patients suffered as a result. To go into work and know im going to get verbal and physical abuse from patients who as so frustrated for reason completely beyond my control but im the only person they are seeing to take it out on. But its also the most rewarding area of nursing i have ever done - when the systems work.
