Pressed my left foot to hard on a peddle felt something crunch been in pain ever since, had x-ray doctor said i, ve got arthritus and live with it. i feel a pad underneath foot and cannot walk.

Pain is a sign that: Something's amiss. A podiatrist or an orthopedist can evaluate further ; prescribe treatment, which may include physical therapy.

Best to be seen: If you cannot walk after having this happen, I suggest being seen again. It is possible that you have a fracture that cannot be seen on a plain xray. It is not uncommon to find a fracture on an MRI that cannot be seen on plain xray. Hearing a crunch sound and not being able to walk are good clues of a possible fracture. I suggest elevation, rest, and crutches for now to prevent weight bearing.
