Okay so first off, no one has squeezed or hit her. She says this just started showing up on its own a couple days ago, and she has been to the ER twice to no avail. They can't figure out what's going on. She has to massage her arm to keep her blood flowing through to her fingers. She says it hurts really bad and she can't move her arm. She is 77 years old. Please has anyone seen this??

She is a bit overweight and I am not sure if that would cause it. Her entire bicep area is yellow and purple and it feels hot. Blood tests showed no infection. X-rays showed nothing.
