How Can A Painful Bruise On The Thigh Be Treated?

Hi, I took a nasty fall from a ladder about 4 months ago. I landed on my right side and the border of a table hit my right outer thigh. I had a burning sensation and a lot of pain. Immediately I put ice and elevated my leg through the night. I also applied arnica gel and stayed away from exercise for a few months after my fall. My bruise was bright red, about 4 inches wide, then it went through the normal color changes...blue/purple and then green and yellow. However, there is a part of my bruise which has not entirely cleared up. There still seems to be a dark shadow that has faded quite a bit since my fall, but it s still not completely gone. I have a dent in that area that feels tender and hurts when I touch it. However, my range of motion was not affected and I feel no pain except for when I lean on it or accidentally bump it. It is not swollen or red. It s just flat and there seems to be a shadow left over. Is this part of the normal healing process? And will it take a couple more months before I m healed?
