Anyone had any experiences with proteinaceous kidney cyst? Cat scan found a simply cyst on my right kidney, along with what appears to be a proteinaceous cyst. Have a cat-scan in another 3 weeks to see if it changes. Also have to have my gallbladder removed soon, as they found a polyp. Dr's also are sending me to a rheumatologist, as they also think I have fibromyalgia. I've got so many things wrong, he said they can't pin-point anything. Having a lot of pain in my rib area, knee joints, back, shoulders? Any had any experiences they can share.
