Does anyone exprience a tingling hot left arm?

I had this on and off today at work... and Iwas really starting to get worried. It didnt help that a lady I worked with made me worse as her husband had a heart attack lst year and she was worried about my symptoms..

I am having a stressful time at work and am very unhappy there so I think the symptoms are ther because of that...

I just wanted to know if any of you experience this?
