[Shimmy]

I had an inflamed sternum from having a really bad cough for a week. I ended up going to a chiropractor (a really good one, most are quacks) and he did some different exercises with me and had me rolling out my chest with a lacrosse ball once a day. It slowly got better and went away. waiting around for it to get better isn't going to do shit. You need to see a chiropractor or someone who specializes in sports injuries.
