I Am Under A Lot Of Stress At Work. The

I am under a lot of stress at work. The other day I didn't sleep well. Late morning I experienced what felt like a Charlie horse on my neck and the back of my head, felt like I was going to faint, and my arms were weak, could hardly lift them. Lasted about five minutes. Have never experienced anything like it, thought I was having a stroke! Seem okay now, but the stress from work is still there. What was that? How can I handle it if it happens again? I take liprinsol for blood pressure and Oxybutynin for bladder control.
