Krankee:
The only vehicle I’ve managed to roll was a Range Rover. It was a long time ago before seat belts were compulsory. It was on the M6 where an artic driver decided to change lanes suddenly leaving me nowhere to go. The corner of the vehicle was heading directly for the drive axle of the unit.
Doing the rounds at the time was the article, “Death in 7/10’s of a second.” (It is now on the Web and I think I put a link to in the old forums). Anyway, with the contents of the article in mind, instead of leaning back, I leant forward almost against the steering wheel, with my elbows bent, with the result that, on impact, I simply slid up the steering wheel. The vehicle then began to roll, ever so slowly, it seemed, firstly onto its side, and then onto its roof, and I found myself sitting in the roof lining. Suddenly there were two lanes of abandoned trucks as drivers came rushing to help. Thanks chaps, but I refused to get out until I had found my ■■■■.
My only injuries were bruising to the tops of my thighs where they had hit the steering wheel.
Whiplash, yes I’ve had that, not only in another accident, but also in the form a being hit over the back of the neck with a table lamp. How that happened is another story. Following numerous X-rays the Hospital were undetermined as to whether a vertebrae had been fractured or not. Treatment: Wear a neck brace for two weeks. Two hours, morelike.
Anyway the discomfort continued, off and on, for a number of years. Nothing debilitating, just that I’d be sitting watching television and my neck would ‘lock’, and I’d have to rotate my head to relieve the discomfort. More irritating than painful.
Being a long time sufferer from back pain, and having found the best treatment to be from an Osteopath, at the end of one session with him, I happened to mention my neck problems, and after a quick rummage about, he put one arm around my head, the other around my chest, and yanked. Click. 
After something like ten years of irritation, I’ve never had so much as a twinge since, (in my neck, that is. 
The back is still knackered.)
Jacqueline. You have a claim pending. Don’t be rushed into settling for an early claim. A friend of mine who also suffered whiplash injuries held out for something like eight years before her claim was settled. I’m sure you will already have had advice that, once liability is accepted, an interim payment can be made. Don’t fall into the trap of dismissing ongoing discomfort in the pursuit of monies to meet immediate needs.
You mention an appointment with a specialist in the distant future. In the meantime consider an appointment with both an Osteopath and/or a Chiropractor. Each will cost about £30 for a Consultation but, if they are of good repute, they will tell you whether or not they are able to treat your injuries. And, you can add the fees to your compensation claim.
Don’t be put off that just because you are in the NHS ‘system’ that anyone will resent you seeking ‘alternative’ therapies’. My former GP had ‘spinal complaints’ as a Specialist Interest. However, he also understood the benefits of treatments not available within the NHS. To claim the fees for the Osteopath under private health care insurance I needed him to sign the forms.
Hence I would hobble into his surgery and the conversation would go something like this:
Doc:- What can I do for you? (As if he couldn’t see) 
Me: It’s my back again, I need you to sign the form.
Doc: Do you want me to prescribe painkillers?
Me: No thanks.
Two minutes tops. NEXT PATIENT. 
Jacqueline. Get well soon.
Talk about getting it together at the appropriate moment by ACTUALLY REMEMBERING the correct procedure during your accident 
! You’ll be fine in any vehicle with smearserver then.
I met the ambulanceman who attended the scene last year, turns out he is a mate of my mum’s partner.
And you got to get it while you can! (The sunshine, that is. 
Eventually found my arm after breif search. Where my shoulder was there was just a tight bit of skin over a hole, and it felt unusual. I remembered thinking that as there wasn’t any blood it had to be around here somewhere as it wasn’t where it should be. Of course, I had to have anesthetic repeatedly to get it back, about 4 hours later.
And as usual, i am the last to know?
