Scanned
Bit the bullet and checked in to see Eric at Bodybalance. The location gave him some concern but he didn't think it was a stressy, most likely to be combination of bone density, calf strength and (lack of) ankle flexibility putting too much load on tibia and winding up with a break down somewhere. Must admit that really made sense as the issues came mainly after rolling my ankle 3 times (it's still slightly swollen). Result was get an MRI booked in, rule out stress / bone issues and move forward from there. No cycling or running until we were sure what the issues was.
