Hi did that title catch your eye, well not 1/2 as hard as my bum hit the road. I was out on a chesnut mare, she will be nameless as it was a feak event, riding in company , I patted her on the shoulder as a thank you , I had ben tightening my girth,but  I had forgotten  this was a manouver that makes her edgy, and then a lorry loaded with scaffolding went past, rattling and too close, she reacted by bouncing and bucking in fright , I parted company on the 4th bounce, and hit the road, luckily my riding hat protected my head, so it was just my coccyx and bum that got squashed, I  rolled out of the way quickly in case she stepped on me, extemely unlikely, horses don't lke doing it , and then crawled to the pavement, I was in pain, but manageable, walked home and had a bath, which didn't help, and went to bed, but the pain kept getting worse, so I spoke to the local Doctor who said needed to go to A & E , he called an ambulance, which took only about 2 hours to get here, went to Bangor, was given more pain killers, x-rayed told nothing there and could go home after supplying water sample , no prob said I , 2 cofees, 4 teas, 6 waters and 4 hours later I did and we went home,ouch.
