What Causes Severe Pain In Thigh?

Hello Doctor, I fell over and hit my thigh on the pavement curb as well as twisting my ankle and straining my foot. This was 8 weeks ago. My ankle and foot are now better. However my thigh is still in pain especially when attempting to kneel down or get back up. My thigh has a dent in it when the collision happened with the curb. It is 1cm deep, 2cm wide and 5cm long horizontal across my thigh. Is this a concern and what can I do to get the shape back to normal?
