I am a fit and healthy sports loving guy (35 years old, 6' 4" and 17 stone). I never had any issues with my coccyx before, until a road trip across Europe left me in agony. Two journeys of 14 hours in my sports car in the space of two weeks and suddenly from no where it felt like someone was sticking a hot poker on my tail bone when I stood up.
I ignored it for a couple of weeks and then finally decided to go see my GP, she told me it was probably bruised and it would go away. I wasn't so sure, there had been no real trauma to cause any bruising, I hadn't fallen over.
As I always do I googled away looking for solutions or ideas of how to fix it, I bought a cushion, did some yoga and stretching but nothing really improved it. Whilst googling I came across the Sayer Clinic, which fortunately for me, was only a 10 minute drive from my house. I booked an appointment with Dr Michael Durtnall (Mike) (see Doctors and specialists in the UK, London) and went to see him.
The initial meeting I told him about my lifestyle, all day in a chair at the office in front of the computer. I was the classic patient. He had a feel of the coccyx area and then took a few x rays. He has an x ray facility in his office so the results were instant. The x rays showed that my coccyx had become misaligned and there was a little bit of arthritis as well.
He did some treatment manipulating the coccyx (all external thank god!!!) and told me to come back next week. By the time of my next visit there were already significant signs of improvement, 60% better than last time I believe I told Mike.
So for the next 3 weeks or so I saw him once a week. After 3-4 sessions I was up to 95% better and now I see Mike roughly once a month just to keep things loose. It is now pain free, with just the odd twinge if I ignore Mike's advice and find myself slouching.
Mike is exactly how you think a doctor should be when you were a young and innocent child, before the reality of the NHS set in :-) he is genuinely interested in your issues, really wants to help you recover and is thoroughly engaging during treatment sessions.
He also looks at your whole lifestyle seeing where you can improve things. I cannot recommend Mike highly enough, he is an extremely knowledgeable Doctor and a real gentleman as well.
