i would go get it checked out it could cause problems if you don't the dr will want to see the bump so he can evaulate it see what caused it could be one of many things i would go get it checked out
Is it big? Is it red? Does it cause a lot of pain which can make you not walk? If it does, I think visiting a doctor is the best procedure right now. "Prevention is better than cure" -Desiderius Erasmus
Not red and can walk on it most pain when i touch it
