Sorry to hear your not well again Lynn
Hope you feel better soon!
I was actually in and out of hospital last year with lots of strange symptoms, A&E do tests to make sure your life is not in danger and then release you without ever really finding out what is wrong.
Must have been seen about 8 or 9 different GP's and got nowhere!
Eventually my mum dragged me to a herbal clinic here in Leicester, i know some people laugh at the though of flowers making them better

but the doctors there are SUPERB. I had a full hours consultation and the lady was almost as caring as my own mum!!

she got to the bottom of my problem and i have been getting well, even if you dont want to use herbal medicine you could still go and see her.. i am sure she will get to the bottom of it. She even diagnosed my mum correctly after GP's failed to, then told mum what to say to the GP's and what tests to ask for!
Consultation is around £60 for an hour but is worth ten times that imho. Might be worth thinking about because your obviously getting nowhere with conventional docs and we all want to see you well again!!!
