The key symptom of Osteoarthritis is joint pain. It can range from mild, uncomfortable pain to severe, disabling pain. Most of the time, this pain comes from using the joint and will fade over time when rested.
As Osteoarthritis advances, the pain can persist while resting and even occur at night, while sleeping. Osteoarthritis can cause joint stiffness, preventing bending and full range of motion of the joint.
