How To Reduce Swelling In My Leg After The Bike Skid In Ghat?

Hello doctor. My bike skid on the Khandala ghat on 5th July. There was some swelling on my right leg (knee) which is almost gone (around 15% is still there). I am able to move freely from the same movement as I drove the same bike immediate back to Pune (75 Km). I had applied Hamdard Herbal Ointment but since yesterday I am feeling pain in my right leg but I am able to walk freely with some strain. So what should I apply to get rid from this pain
