I've been having some pain in my right foot recently, specifically the base of the big toe. Has really limited my section hiking this year. Finally got it checked out by a good sports medicine ortho, and the diagnosis is a sprain of the ligaments at the base of the big toe, or "Turf Toe". In a boot, taking advil, ice when I can, and it's better, but looks like a couple of months off the trail. Have any of you experienced this particular problem before? If so, how long before you could hike again?
