About 6 Weeks Ago My Right Inner Knee Joint And

about 6 weeks ago my right inner knee joint and left inner knee joint suddenly started to pain me. The pain is all day. It is particular moderately painful when waking. if I turn my knee inward it is a sharp pain. Sleeping at night I can be awakened by a constant mild to moderate dull pain. After sitting for more than 30 minutes my knees stiffen. This came on suddenly and in both knees.
