Hello Robotnik,
Unfortunately there are not a great many Qigong practioners who teach/heal in the UK. Alos don't forget SFQ as a form of Qigong is specifically designed for healing purposes. This is not necessarily the focus of a many other forms.
As far as i know we do not have any Qigong masters of any reknown based in the UK. It is for this reason i myself have opted for SFQ via self-learinging materials and hope to visit Master Lin to learn the next levels next year in the US.
If you contact me offline i could advise you what's on offer in the UK if you still wish to go down this course but you may need to travel a bit. Have you given SFQ a try? I strongly recommend that you do. If you tried already can you describe to us what you are doing? At least buy Master Lin's book available on his website as it has the basic exercises in there.
Also if you give us a few more details about your blockages we should be able to help you on this forum.
