Suggest Treatment For Swelling And Pain In Knee

I am an active 48 yr old female. As I finished a serve yesterday during a tennis match, I had severe pain in right knee. My acl has been reconstructed twice (1988, 1995). I wear a donjoy knée brace when playing. I have some swelling, burning sensation and pain on extension. I have taken ibuprofen and iced it every few hours. Do I need to see a dr or give it more time?
