How can I tell the difference between inflammatory (e.g. rheumatoid arthritis) and mechanical (osteoarthritis) joint diseases?

Check out the symptoms and see where you might fit in. The symptoms include morning stiffness, pain, reaction to a cortisone injection, joints involved and more.

Does activity increase or decrease the pain?The longer you’re inactive, the worse is the pain. Rest worsens the symptoms, activity improves the symptoms. Be active!Activity tends to increase the pain and stiffness, and rest improves the symptoms.
Morning stiffness?You wake up with stiff joints, but it improves after an hour or more. The more you use your joints, the sooner the stiffness subsides.You wake up with stiff joints, but the stiffness lasts 15-30 minutes, then it becomes easier to move.
