Hello I Have A Few Questions About My Mother Is

Hello I have a few questions about my mother is 54. Can you help me out...she has been to multiple apointments and has had several tests run and still has no answers as to what is wrong.
She has had an angiogram, colonoscopy, x-rays, ultrasounds (pelvic and abdominal) and several pages of blood work. Here are a list of her symptoms: severe swelling from her breast plate down with a distended stomach that now droops onto her legs, no upper body swelling other than a possibly puffy face in the past few days, constant pain and pressure in the lower body (abdomen down), short of breath, fingers tingle and change colors (dark purple) when she went to the ER they could not get her oxygen levels from her fingers. Toes do the same thing.. On December 22 she weighed 103, on Dec 29 she weighed 110, today she weighs 111.8. He normal weight is in the 90's and has been for at least 15 years.
