You may have seen a TV illusionist series earlier this year. One of the illusionist tricks was to drive a huge truck over the illusionists chest while he was lying on the ground. They showed how it was done. Just like the photo above. The truck is heavily loaded on one side, so there's no weight on the wheel that actually runs over the person.
That woman would also make a very good Olympic sailoress, where a similar skill set is required. Leaning right out of the boat allows the sails to take more wind without the boat capsizing. It's a very useful techinque.
In my limited experience that NHS phone-advice helpline is completely useless. If you still have a problem after 3 days you need to see your GP. Bear in mind that it may take several weeks to secure an appointment.
Also, it may not be too late to try start growing lots of veg (maximum range of colours is important) and stuffing yourself with every kind of plant that might contain anti-oxidants. Don't forget water cress.
