Medical evaluation: can provide you with an accurate diagnosis - all we can provide you with is a guess.

Please have it: examined immediately as anything that healed properly should not have symptoms like this a year later

Bump: You may have a hematoma which has calcified over time. A bone bruise which can last for months can also be a possibility
