Have you ever tried any doctors in Sioux Falls? I am questioning if this is what I may have and just read your post on the horrible doctors in Sioux City. I see Dr. Andrawis in Morningside. He is wonderful! But I am scared to see a specialize in Sioux City. I have had issues with CNOS before and really hard for me to do back out there. I see my doctor on Tuesday and I am going to see if I can see someone in Sioux Falls. I will let you know how it goes.
