Been having pain in the shoulder, roughly in the collarbone, but also less frequently in the shoulder point. In addition, there is a point of sharp pain in the back, roughly halfway down the ribcage. The pain is at its worst when I lay down flat on my back, which is how I would normally sleep. When I breathe, I can feel the left lung almost scraping in the pain point, like I can feel it skip across. I haven't been able to get more than two hours of continuous sleep for the last ten days, so needless to say, I'm not feeling especially sharp, so my apologies if this sounds off, or the information is insufficient. The pain is in the middle of the second week. The first few days, I was fairly certain it would pass, but now I'm starting to get a bit concerned.
I'm a twenty-nine year old male, 5' 5", heavyset.
