I had an episode the other night that scared the crap out of me. Was doing dishes when this deep, burning, severe pain spread across my back, just below my shoulder blades, then down the back of both arms. I went to sit down and started to get clammy. The pain was excruciating. I couldn't move. I couldn't lift my arm. Husband asked if my chest hurt and it felt like the pain was wrapping around to my chest by then. He called 911. By the time the paramedics arrived, the pain had subsided, of course. They took my pulse, temp, blood pressure and did an EKG. Everything was normal. Said it could have been a pinched nerve. I honestly thought I was having a heart attack. I have had several milder episodes of this type of pain before, but nothing this severe. I was completely debilitated for a few minutes. Any ideas?
