For the past three nights, I have been having terrible pain down my arms. It starts at the elbow and goes into my hands and fingers. It is horribly painful and wakes me up. My fingers go number and tingle it is getting worse. This is a new symptom for me. Also, this morning I had a purple line on my left hand that ran from the end of my had to the middle of my thumb and forefinger. After I showered it went away. Also, last year the tips of my fingers were blue for several hours. Has this happened to anyoneelse?
