It is unfortunate that many doctors will not make a definite diagnosis or start any type of treatment UNTIL your symptoms develop into a specific disease. At this point, you could be showing early symptoms of so many auto-immune disorders that they are unwilling to do much about it.
However, at this point, you are well within your rights to demand that they do something to treat the symptoms that you are displaying so that there might be a possibility of preventing them from developing further. Or, at the very least, to give you some relief from your symptoms.
I hope that you are able to convince them to do more than sit and wait!
Peace and Blessings
Look For The Good and Praise It!
