Hello the other day I fell. That night I felt tingly feeling along with my fingers going cold. There was swelling in my elbow and side arm. I couldn't go to sleep at all. The next morning my arm was swollen and look to be purplish my fingers were swollen I tried to move my hand when I couldn't bend them all the way. If I try to bend my fingers my hand will become white. With the swelling there is numbness. I have tingly feeling in my arm and down my back. I am not sure what it is. I talked to someone and they said that I could a bruised my arm but it does not feel like that. Can you help me try to figure out what could possibly be causing this?
