Determining the cause for your symptoms, which will then determine the best treatment, requires the performance of a history and physical examination, and sometimes, imaging studies.

The severity of your knee pain, the fact your knee has been swelling, and the knee buckling symptoms your describe are each, by themselves, reason enough for you to be evaluated by a physician.

Despite the fact you recall no specific knee injury, there could be degenerative ("wear-and-tear") changes in your knee which have reached the point where they're now causing symptoms, for example, a degenerative meniscal tear (torn cartilage), arthritis, or a patellofemoral problem (involving your knee cap).
