You poor thing, you sound very frightened and desperate for answers. It's extremely difficult to function with working, raising a family, running the household and getting people to believe you when they can't see an obvious reason for your discomfort and it is totally disheartening when your much loved family and friends disengage and begin the "get over it" and "pull yourself together" blah blah blah. I'm so very sorry you are facing this without some definitive diagnosis and I totally understand your frustration, pain and angst.
There are a number of supportive folks on these threads, many who face what you do and have similar challenges. We are not only on this thread but on the RSD/CRPS, chronic pain etc. Often just being able to be understood and knowing you are not alone can bring a sense of relief. Feel as well as you can do and know we believe you, you are not crazy.
