I am a new runner in fairly good shape. I began running last summer and within 3 weeks had a stress fracture of my tibia. Upon recovery, I diversified my training to include hill sprints, weight lifting, swimming and cycling and ran very little. Within 2 weeks of running again, I stress fractured my tibia again, same leg, different place.
I have great, new shoes professionally fit to me. I am not overweight. I do not smoke.
I have a normal DEXA scan, low vitamin D (but higher than it has been), normal thyroid and parathyroid results, normal blood calcium levels.
I have had 4 children in the past 8 years and nursed them for a total of 5 years. This means out of 103 months, I have not menstruated for 84 of those. I expected a DEXA scan to show any depleted reserves in my bone density but all of it was normal.
I want to start training for a sprint distance tri in June but at this point, feel like I'm going to have to keep running in the pool until the week of the race!
Anyone have any ideas? I'm out of them and getting really frustrated!
