Medial Tibial Stress Syndrome
Tibial stress fractures can be exquisitely painful, but are typically only painful whilst running and sprinting, unless doing longer distances when even a jog may be problematic.
This is a particularly common problem in military recruits and those who take on a new training regime. Likewise, athletes who develop this in the middle of a training regime who ramp up their activity a bit too rapidly can struggle with this.
Pain is normally very localised to one particular spot on the back-side of the tibia on the inside of the leg,, but may also be generally tender in a region approximately 6-10cm in length.
Managed with a mixture of orthotics, footwear, strengthening and managing your activity levels. Other strategies for the treatment of Medial Tibial Stress Syndrome exist, but are not usually necessary. Sometimes including other specialists may also be necessary.
Arguably the proper diagnosis for 'shin splints' this is a stress fracture that occurs along the inside of the shin bone.
