What can be done for a possible soft tissue foot injury?

Depends on injury: Rest and ice/elevation for simple injury without structural problem. Ligamen tor tendon injury or tear require immobilization and sometimes surgery.

Ice: Rest, elevate. If pain persists or becomes worse see your podiatrist.

Ice,elevation,rest: Doing the 3 things above plus a tincture of time will help you get better .Also antiinflamatories will help.

Depends : On where injury is on foot and how it affects function. Initially ice will help. If more than 2-3 days old try heat. Rest and offloading area. Anti-inflammatory medication may be helpful. If still a problem, see podiatrist for evaulation and treatment.

Try Up and no Ice.: If it is only possible soft tissue injury, do very little. The body's natural defense and repairative functions will kick in very nicely. If it is a blatant injury the by all means , begin with the RICE protocol.
