I just happened to come across this website for thorasic back pain. Therefore, I am new to this site. I am a 49 y.o. I have been a production welder for the past eight years, recently moving into the shipping and receiving department. I have had chronic thorasic back pain since mid 2005. I was in the process of losing weight through WW and joined a cardio-kicks class which I absolutely loved. I was down 70 pounds, doing great with class but was beginning to have problems lying on my back doing floor exerices or laying across the exercise ball doing ab exercise that involved some twisting. I just could not stand to lie on my back and to this day I still have problems lying on my back. The pain is chronic and not much alleviates it. Meds, physical therapy, massage, injections, heat, ice and tens unit only temporarily mask the pain but at night when trying to sleep is the most painful. Sudden movements, sneezing, stretching, straightening up or other movements cause pain. Needless to say that I have gained back most of the weight and an feeling quite depressed about that. I just want the pain to go away and I am frustrated about what might be causing the chronic pain. Well on that note I need to get up and moving as I have arthritic hips and stiffen up if sitting too long.
