I had suffered with horrendous esophageal spasms for over twenty years. They came at random times and I could never tie them to a trigger. They can be best described like Charlie horses you get in your calf but they could last for hours all the while getting longer, stronger and closer together, like labor pain. These episodes (sometimes weekly, monthly or farther) absolutely made me out of my head in pain. They are often mistaken for a heart attack. I have now been diagnosed through biopsys with Barrets Esophagus and am now on a proton pump inhibitor. Thinking back it has been possibly 18 months to a year since my last spasm... Possibly cells changing in esophageal lining could have been causing spasms? I also have bouts of Costcochrronditis that make breathing painful. On top of these rather obscure conditions I injured my back at work on January of 2014 and it was a sprain that does not show on xray or mri. My back doesn't want to heal and I now have back spasms that are agonizing. My Ortho Docyor thinks maybe a Facet Joint with some slack in it is the culprit. Also there is a clunking in about the T-12/L-1 junction when I lay and do a specific movement in range of motion stretches. I am beginning to get very depressed and feel like I'll never feel better!
