A painful callous on bottom of pinky toe i've clipped off with sterile nail clippers numerous times over the years painful when it returns?

See a foot doc: You get the callous due to friction. If you can elimikinate the friction or that which is rubbing you can solve your problem once and for all.

Likely: The position of the end of bone is getting more friction thus the callus. Many treatments available.

Have it evaluated: Some causes of corns or calluses include: friction, pressure, repetitive trauma, and a limitation of joint motion. You may benefit with the use of a special topical moisturize and the use of a pumice stone or an emory board. Consult with your podiatrist and determine the best approach for you.
