right leg was hurt somehow. pain is on right quadracep? and the knee is stiff. hydrocordone dulls the pain
Well, without an evaluation it would be difficult to say. I would suggest getting this examined by an orthopedician or a primary care physician for an accurate diagnosis and appropriate management. Meanwhile you may continue resting the knee, avoid weight and movement is possible. Ice-packs and NSAIDS may be helpful for pain relief as well.
Hope this is helpful.
