Hi. I am new to this site and I am not sure this is a spinal problem. I have not been to a doctor for this. I have been feeling this locking, freezing pain in my upper back, chest arms and hands where I freeze and cannot move my arms for about 5 minutes at work. The heavyness stays around for most of the day. I have to stop typing or writing for a while so the pain subsides. Sometimes it is so painful it feels like a heart attack but I keep thinking this is probably from my neck injury I had at 18. I am 49 now. I looked around this site but I couldn't find an answer. I hope it is ok that I write for advice. Thank you.
