question: I recently had fluid around my heart, went to ER, they drained it. Fluid caused bottom of my lung to collapse. I was told that I might end up with pneumonia and I'm pretty sure I do. Lungs hurt. I'm experiencing pain in my upper back, near bottom of shoulder blade, just to the left of my spine. It feels like a pulled muscle. Would it be advisable to apply ice and heat to my back, or would this be a bad idea because of my lung issues? I will be headed to the Dr. tomorrow for a follow up.
