See your doctor if you think you have osteoarthritis. There is no definitive test to diagnose the condition, so your doctor will ask about your symptoms and examine your joints and muscles.
Your doctor may suspect osteoarthritis if you:
are over 50 years of age
have persistent joint pain, which gets worse the more you use your joints
have no stiffness in your joints in the morning, or stiffness that lasts no longer than half an hour
If your symptoms are slightly different from those listed above, your doctor may think you have another form of arthritis. For example, if you have joint stiffness in the morning that lasts longer than an hour, you may have a more inflammatory form of arthritis.
Further tests, such as X-rays or blood tests, may be used to rule out other possible causes of your symptoms, such as rheumatoid arthritis or a fractured bone.
However, they are not always required to confirm a diagnosis of osteoarthritis.
