Daughter Had A Cyst Lanced At Hospital That Was Infected.

Daughter had a cyst lanced at hospital that was infected. She is type 1 diabetic & was in dka when she arrived at the hospital & they gave her 5 bags of fluid. That was 10/14. The following day her legs and thighs swelled up and swelling going into her groin & up her back. All is very painful & she can hardly walk. They have checked her heart, checked for blood clots, did a test to check the veins and arteries. It's been 7 days and the doctors still have no answer. Can you help?
