Hi @linda2114 i can only imagine how frustrated you are feeling. I, too, went through several months of being brushed of, told it was all in my heat, etc. But i knew it was real. My sister has been diagnosed with an autoimmune disease 3 years earlier. I finally got a true diagnosis at the university medical center near us.

Then, my sister starte looking at the families genetic ties to autoimmune diseases. Here is the link she sent me.

The article helped us answer many questions
The doctor mentioned mixed connective tissue disorder. Did he/she suggest any treatment or plan for further testing?
