the most common forms of joint pain are osteoarthritis, rheumatoid arthritis, and posttraumatic arthritis.
The National Institutes of HealthOff Site Icon (NIH), describes each as the following:
Osteoarthritis (OA): OA is the most common form of joint pain. It causes pain, swelling and reduced motion in the joints. OA occurs most often in the knees, hips, hands and spine.
Rheumatoid arthritis (RA): This form of arthritis causes pain, swelling, stiffness and loss of function in the joints. RA most often occurs in the fingers and wrists.
Posttraumatic arthritis (PA): After an injury in the foot or ankle, PA can develop. It causes cartilage between the joints to wear away, and can develop years after the injury.
There are more than 100 different forms of arthritis and related diseases. The most common types include osteoarthritis (OA), rheumatoid arthritis (RA), psoriatic arthritis (PsA), fibromyalgia and gout. All of them cause pain in different ways.
Here aresome common types of the disease to watch out for.
The most common form of arthritis in the world, osteoarthritis (OA) is known as a “wear and tear” disease. It typically targets weight-bearing joints — the feet, knees, hips and spine.
Many people believe OA is just a natural part of getting older. However, that’s not completely accurate. OA can also result from injuries or obesity, both of which put extra strain on your joints.
In OA, the cartilage that caps the bones in a joint begins to break down, so you lose your natural shock absorption. In turn, you start to feel an aching pain in the joint, especially when you move it, and stiffness that’s worse when you wake up in the morning. You might also notice swelling and heat, and your range of motion will decrease.
2. Rheumatoid Arthritis
Unlike osteoarthritis, which comes on as joints are strained, rheumatoid arthritis (RA) begins with an overactive immune response. As your immune system mistakenly attacks your healthy joints, inflammation increases, leaving you with pain, swelling, and in the worst cases, disfigurement.
The pain and extreme fatigue of RA can be difficult to handle, but the physical damage it causes is even more serious. If the condition isn’t brought under control, joint damage can be permanent, and the dangerously ramped-up immune response can begin to target other areas of the body, like major organs.
RA symptoms can bear some similarity to OA symptoms, but they’re often more severe and appear in a symmetrical pattern (that is, if the left wrist becomes inflamed, so will the right wrist). Morning stiffness will also last longer — for some, it can stretch well into the afternoon.
3. Psoriatic Arthritis
Psoriasis, like RA, is an autoimmune disease that attacks healthy tissue. The skin is the most common site of symptoms, with thick, scaly plaques spreading over the arms, legs, chest and scalp. Between 10 percent and 20 percent of psoriasis sufferers will also contract psoriatic arthritis, which manifests as swelling, heat and pain in the joints.
Psoriatic arthritis can vary in severity: some people might only experience symptoms in one joint, but for others, several joints are affected. It often hits the fingers and toes, causing knuckles to swell and the nails to thicken, pit and chip away.
For most people with psoriatic arthritis, the skin symptoms of psoriasis come first, and the joint symptoms show up after age 30. However, psoriasis is unpredictable and the symptoms can come and go at any age
