What can i do if my index toe swells up when ever i run for a lot?

See foot doc: So he can take an x-ray. Maybe, you have. Fractured toe that won't heal cause you keep running on it.

Toe swelling: Try different shoes, and make sure they are secure on your feet when running.

Shoes: I suggest you start by getting fit for running shoes. Go to a running store.Sometimes running down hill can cause this.

See Podiatrist: Have it evaluated and determine if there is any condition that is causing this. Then treatment can be started if necessary. Also try changing running shoes.

See the foot doc: I would have it x-rayed to see if anything wrong with the bone. I would make sure your wearing the proper size sneakers. That would be my starting point.
