### input:
Hello, about a week ago I had fallen down the stairs and landed on my back. It knocked the wind out of me, but after that I was only sore for a few days after. Two days ago, I had an attack where my back muscles started spasming, and it got to the point to where I was gasping for air. I had went to the ER and waited for about 4 hours and still wasn t called back so I just went home to sleep because I was extremely exhausted. I ve been alternating cold and hot compresses to the area that s most sore. Last night and tonight when I lay down to rest my back I hear crackling noises in my lungs, but they feel like they re pressing up against my ribcage. I can breathe, but it does hurt when I inhale deeply. I have insurance, but it s not all that great and I don t really want to have to go and get it looked at if it s something that will solve itself if it s a pulled muscle. The muscle is right behind my ribcage, close to my kidney region.

Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having blunt back and chest trauma. Since you are having muscular back pain with breathing difficulties and cracking sound from lungs, we need to rule out these possible complications. 1. Rib and vertebrae fracture. 2. Pulmonary contusions3. Pneumothorax4. Muscular injury. So get done chest ray and x-ray of doraolumber spine to rule out all these. If both are normal than mostly you are having muscular pain. Try to follow these steps for better symptomatic relief. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Take good painkiller and muscle relaxant. 4. Apply warm water pad on affected site.
