Hello evo123
They have excluded almost everything,
blood work,
blood sugar,glucose tolerance,hypoglycemia (although I often feel like that),liver values,kidney function,heart problems,MRT,thyroid and some other stuff....
If you want to know what`s all wrong you can look at the group NEUROLOGICAL LIMBO LAND, in which I am also a member and where I have posted the thread "Neurological or Autoimmune- something strange related to blood sugar".
