Re: Swollen Metatarsal Ligaments (I think)
I think you may have what's called Metataralgia, the metatarsal heads have been bruised and are now painful and swollen. There is nothing that can be done medically, but the suggestion is to ice your foot, rest, raise the foot, wear only upportive shoes, don't go barefoot or wear heels (for women). They have some support pads you can use on the bottom of your foot to help strengthen the area so the reoccurance can be reduced.
Google it for more info.
The only reason I know of it is that it appears it's what I have too.
