Yes! Mrr I've experienced the very same symtoms. My supervisor at work wasn't taking any chances and insisted I take an ambulance ride to the hospital. I was rushed to the hospital one March day from work with chest pains. In March the potholes are very pronounced in the state of Maine and as we rode over every one of them over Witch Spring Hill, the EMT tried to find a vein to stick a needle into...not good. He poked and poked with no satisfaction. I was restrained the whole time, but my howling in agony only made the EMT probe more frantically. It turned out that I was experiencing an esophagal spazm caused by acid reflux. The spazm had subsided by the time I reached the hospital, but the black and blue spots on the inside of my elbows lasted weeks.
