My Mom Has An Autoimmune Disease, And Has Been To

My mom has an autoimmune disease, and has been to see many doctors. She was in the hospital for two months with legionella pneumonia, and was on the vent for two weeks and nearly died. She's had this autoimmune disease for three years, and we are losing faith in finding a doctor that can help her. We live in Ohio, and can't go any farther than there. She has an appointment at Cleveland Clinic, but the doctor she's seeing does not specialize in autoimmune diseases. Please help
