I have a physical job that's none stop, and I'm constantly moving around, could I have possibly strained my chest area or something. I'm going to the ER because this is the 2nd day of pain. When I breath in deep it hurts like a sharp pain, and when I lean over to bend down to grab something it hurts and it also hurts to even turn over in bed. I took Ibpro. for the pain and it would make the pain stop for only a couple of hours.
