My foot is so swollen and bruised. It even hurts to walk on. And this is not minor pain, it hurts a lot. It started out a couple weeks ago with just pain when I ran and some swelling and bruises. However, I ran through the pain and it kept getting worse and worse. Now at this point, I am still running everyday (up to 10 miles a day) with this excruciating pain on my metatarsals. When I rest it, the pain subsides. The spot is tender to touch and is pretty localized. What may this be and should I stop running?
