I would of late rest the knee as much as possible for a week or so. Follow the R.I.C.E. method:
REST: Rest and expulsion of activity which aggravates the injury.

ICE: Apply Cold to stop spasm and restrict excess Fluid to the injury.

COMPRESSION: To further inhibit swelling caused by excess Fluid to the injury.

ELEVATION: To further inhibit swelling cause by excess Fluid to the injury.
Take an anti-inflammatory such as ibuprofen to help next to the pain and swelling.
Note; Going to a Doctor after doing the above for a week or more will show the Doctor that you are not only just whining, that you took action to try to restore to health the injury yourself and the Doctor will not send you home describing you to do just what I recommended. The Doctor would be aware of more comfortable having it scan if you took the above action and it did not resolve itself.
GOOD LUCK!
Could be anything from over-use, patella-femoral syndrome, patellar tendonitis, arthritis, meniscal gash, or an injury to the ligaments. I'd suggest seeing an MD, they could refer you to an orthopedic or better yet, a physical consultant.
