I had Professor Finley ,he was the first specialist to find ME ,he was Private ,but was under the Queens Hospital in Romford, Essex. He lives in Gidea Park .Excellent Doctor ,you have to have every single test you can think off. Be cause they have to make sure you don't have other conditions. If that's no help,there a ME clinic at Southend Hospital ,and Colchester .They also deal with FIBRO.
Good luck
