I'm so sorry to hear you're in so much pain. My DIL has been dealing with severe pain in that same area- says it feels like a heart attack and hurts when she moves a certain way. I've seen her laying down on the floor, flat on her back and not moving, trying to ease it. Her dr. gave her some pain meds and diagnosed her with costochondroiditis. I don't know if this is exactly what you're dealing with or not- just thought I'd throw it out there. What DiMarie said also makes sense. What has helped my DIL the most is going to a chiro and getting adjustments for it. Sounds like you definitely need something for pain though.
