Never felt it this bad before. Just over use. need rest. Diagnosed as Anterior Tibialis Strain. Received steriod injection and oral steroid suppliment. No activity for 1 week after one week of doing nothning but cardio. Tried a couple of miles after one week of injury but was still strained. Still plan on Marathon in 16 days.
Might have been elevated into a chronic compartment stress injury. Need to see a sports doc.
Not CCS, small stress fracture with lots of tendon strain at joining area to bone (tendenitus). 4-6 weeks no running. Keep cardio up with deep water running and cycling.
