Injured by a car in Slovakia which ran into the back of mine causing whiplash: can I claim compensation in the UK?

On Sunday 6th January at approximately 7.30 am I was involved in a motor accident in The Slovak Republic. I am a British citizen and was visiting Slovakia for two weeks (my wife is Slovak and is at present studying in Slovakia). My father in law was driving me to the airport in his car. The road conditions were icy. All of a sudden we had a bid impact from the back, we were hit by an Austrian car, pushed down the motorway and down the embankment and the car ended up on its side. Consequently, I was taken to hospital and had to spent three days in hospital so that all the relevant checks could be carried out. Luckily all the tests were negative. The only injury I have suffered is a whiplash injury and I now have to wear a collar. I am not allowed to fly back to Britain as yet. I have to see a doctor in a few days' time for a checkup. I also have to attend a police interview as a witness as they are pressing the charges against the Austrian driver. As you can imagine, this has caused a great inconvenience to me and my family. I am self-employed and I have probably lost my job as they could not keep it open for an unlimited period of time. My weekly wages average £650.
