Burning pain below knee 4 mths after fall?

[toothgenie]

Has anyone got any idea what this is? I fell on both knees when I missed a step, my right taking most of the force. I did have an X-ray a week later which showed no fracture to the knee cap. The bruising went right down the shin onto the ankle. I I struggled initially with swelling but gradually it has improved. The Gp said after 2 mths that I had a bursitis and prescribed naproxen. That helped and 3 mths after the fall it felt better although I felt an occasional burning sensation and tingling however that stopped until today. My knee is really hot and my shin seems bruised again and the burning sensation is pretty intense.
Is it usual to feel this pain so long after initial trauma, would it be worth asking for another X-ray?

I had a bad knock to the knee about a year ago, it didn't give me much pain initially but about 3 months later it swelled up and I was in agony with it. The pains only mild now but still have trouble with stairs and kneeling down. Everyone's different though, yours might mend better than mine, but the knee can take ages to get better.
