I,m 29 yrs, almost 6 feet tall, about 75 kg, no previous medical history. I was playing with my nephews and slide down a children s slide which was very steep. I completely let go and landed with a bang at the bottom of the slide, on my tail bone. It s been 2 weeks and it s still paining, specially when i sit and more on harder seats. When i lie down it s almost fine. When will it heal and do I need to go in for some X ray or MRI scan???
