Hoo doggies, I'm researching the topic, and there is an overwhelming volume of information on the condition.
Causes: Gout, arthritis, trauma.
Severity: Limitus, Rigidus (several stages), End Stage
Treatments: Stiff-Toed Shoes, Rocker Shoes, Orthotics (an infinite array), Mobility Therapies (a long list), Surgeries (several).
It's a lot to digest and process. And it can't all be true. The only common theme is that the condition is progressive. Terrific.
I have an appointment with my sports injury doc in a week. Until then, I guess I'll continue to fret over my long-term prospects of playing this sport we all love.
