How long do shin splints typically last?

Rest should resolve: Shin splints is an overuse injury commonly seen when a training regimen suddenly increases too rapidly beyond the physiologic capability of the leg bone (tibia) to adapt normally to increased stresses. If rest is not instituted, an overt stress fracture can result. Most respond within 3-6 weeks to rest, limited impact activities and maybe soft boot bracing.

Depends: Shin splints, known as medial tibial stress syndrome, typically last 2-4 weeks with adequate activity modification and physical therapy. Since they occur when excessive stress is put on the lower legs, the recovery rate depends on how long one has been exercising with pain.
