Go visit your doctor: Bulging in the knee can arise from either bursitis, or a cyst related to a torn meniscus. Bursitis typically occurs directly over the knee cap (patella). A cyst will typically occur over the inside or outside portion of the knee (in relation to whichever meniscus is torn). In either case your doctor can help you overcome your symptoms, or direct you to another diagnosis.
