For the past 3 months on and off, i've been having dull pain on the underside of my left arm from the elbow down, and in my wrist. Sometimes it's awful! It also results in my hand and fingers going numb and feeling cold. I went to the er because I thought I was having a stroke or something, and the doctor really didn't have much to say. He said maybe it's carpal tunnel and gave me a splint to wear. Sometimes it helps and sometimes it doesn't. I do not spend much time at a computer and am not left handed. Please post and let me know if this sounds like carpal tunnel or something else! Thank you!
