Dunno. Stress fracture? Tendinitis? Alien parasite?
Orthopedist visit and x-ray on June 1 were inconclusive; bone scan scheduled for June 7 and postponed to June 14.
June 14: Bone scan (with Technetium-99m) revealed increased circulation at the point of pain (10 cm below new, medial surface of right tibia) and dramatically increased bone growth. The diagnosis is a stress fracture.
I required about three weeks on crutches and considerable rest from activity to recover. After about four weeks, I started stationary biking and eventually graduated to ellipticals and limited treadmill work. Resuming regular activity took about ten-twelve weeks. Probable cause was excessively rapid build up of training. I consumed lots of calcium, though it's not obvious if that helped.
