Hi thanks for your question.
The bump you are having on your 4th toe is most probably what is called as corn
. Corns are formed on pressure point due to constant friction between shoes and foot. This is due to wearing of tight shoes. Corns are accumulation of dead tissues. Wear shoes which fits
best to your size and avoid wearing high heal Shoes. Corn dressing is also available in market by the name of corn cap, you can also use. With the above 2 steps hopefully corn will disappear, if it doesn’t disappear consult a general surgeon
and get it removed surgically.
Hope this answers your question.
