My Mom Had 3 Surgeries In 35 Days: Gallbladder Removed,

My mom had 3 surgeries in 35 days: gallbladder removed, ER surgery for herniated and obstructed intestine (she was throwing up fecal matter from the blocked intestine) , and a gastric bypass. She has had a very very difficult time with all of it. She is still sick from the hernia repair from Sept. she also recently has been getting sudden purple hands. We are worried about the purple hands, what could this be?
