How does the foot feel when climbing?
Don't feel it at all. Currently I barely feel it at all. Only if I'd stomp on it, which im not doing.
Sound like not stomping on it is a good plan then!
The foot specialist said that there is no evidence of a stress fracture after I had an X-ray.
That's good! But if you don't have an alternative explanation I wouldn't fully trust the x-ray. Sometimes small stress fractures can go undetected so keep being careful with it.
The first doctor said it probably wouldn't show up. I'll see after more appointments.
