Well, going back to late last summer, things were going well, couple of parkruns under my belt and enjoying the running so thought I'd treat myself to some new shoes. Off to a local running shop (part of a chain) gait analysed, 100 quid handed over and off I went with shiny new shoes for over pronators. Shortly afterwards started to feel twinges in right knee but assumed it was just things getting used to new (and of course better ) shoes. Things deteriorated and went to physio at work, he couldn't find anything specific and suggested bursitis. Rest. Still no improvement so eventually went to gp. X-ray, mri and 2 bone scans later it transpires I have a cyst in my tibia (which is irrelevant to the pain) and nice healthy knees (as in the soft tissues) but oedema in the bone marrow at top of tibia, especially on the inside part - where the pain is. Off to specialist physio - turns out my left foot pronates but right foot supinates so shoes were opposite of what it needed, exacerbated my natural wonkiness and led to oedema (bruising) in the bone from it being bashed against femur at every step .
On a slow road to recovery now and rock-taped like a parcel to start realigning muscles until I can build them up myself then may need some orthotics in a pair of neutral shoes. But not run properly for 8 months and missing it like crazy!
Feeling pretty miffed (not to mention stupid that I didn't go with my gut instinct when first twinges started).
So, be warned. Gait analysis def not necessarily all its cracked up to be and shops are there to make money!!
