I Fell Around 10 Years Ago On The Stairs And

I fell around 10 years ago on the stairs and what i think happened seemed like it caused in indent on my butt cheek like the muscle was pushed up. It seems to have gotten worse lately and it more visible which i think is due to toning up that area. I know it has been a long time but should i consult a doctor about it as it hasn't improved or went away?
