Here is a link,
http://www.spinecor.com/default.aspx?pageid=1797 Spinal Correction Clinic, 10 Harley Street London, W1G 9PF but if it's not near to your place you shuld call the treatment center in UK and ask them if there is other closer to your place.
About your condition i don't want to tell you much more because i am not an expert and to much people think on differant way here in this forum and sometime something works great for someone and with the exact same treatment other get worse and it could be quick just like it was for me. Fortunatly i fond the good thing to do after!!!
I can tell you when i was doing lots of cardio i had pain because apparently my thoracic cage was moving up slowly and it's was pinching everything between my colar bone and my first rib. But it was for any kind of cardio, running, biking, rollerblading and more... Also the vibration was giving me hard time but again i don't know for you...
If you want send me a PM and i will give you my breathing exercises because i am 100% sure it could not make your condition worse and i think it could be good for you to see if you can see a differance or not. If it's does something it's gonna be a good indicator. For the rest of my exercises i think it will be safer to see an expert before to ask them what they think about them.
