Arthritis Information
“Arthritis” is not just a word doctors use
when they talk about painful, stiff joints. In fact, there are many kinds of arthritis, each with
different symptoms and treatments. Most types of arthritis are
chronic. That means they can go on for a long period of time.
Arthritis can attack
joints in almost any part of the body. Some forms of arthritis cause changes you can see and
feel—swelling, warmth, and redness in your joints. In some the pain and swelling last only a short time, but are
very bad. Other types cause less troublesome symptoms, but still slowly damage your
joints.
Common Kinds of Arthritis
Arthritis is one of the most common diseases in
this country. Millions of adults and half of all people age 65 and older are troubled by this disease. Older people
most often have osteoarthritis, rheumatoid arthritis, or gout.
Osteoarthritis
(OA)is the most common type of
arthritis in older people. OA starts when cartilage begins to become ragged and wears away. Cartilage is
the tissue that pads bones in a joint. At OA’s worst, all of the cartilage in a joint wears away, leaving bones
that rub against each other. You are most likely to have OA in your hands, neck, lower back, or the large
weight-bearing joints of your body, such as knees and hips.
OA symptoms can range from stiffness and mild pain
that comes and goes with activities like walking, bending, or stooping to severe joint pain that keeps on even when
you rest or try to sleep. Sometimes OA causes your joints to feel stiff when you haven’t moved them in a while,
like after riding in the car. But the stiffness goes away when you move the joint. In time OA can also cause
problems moving joints and sometimes disability if your back, knees, or hips are affected.
What causes OA? Growing older is what most often puts you at risk for OA. Other than that,
scientists think the cause depends on which part of the body is involved. For example, OA in the hands or
hips may run in families. OA in the knees can be linked with being overweight. Injuries or overuse may cause
OA in joints such as knees, hips, or hands.
Rheumatoid Arthritis
(RA)is an autoimmune disease. In RA, that means your body attacks the lining of a
joint just as it would if it were trying to protect you from injury or disease. For example, if you had a splinter
in your finger, the finger would become inflamed—painful, red, and
swollen. RA leads to inflammation in your joints. This
inflammation causes pain, swelling, and stiffness that lasts for hours. This can often happen in many different
joints at the same time. You might not even be able to move the joint. People with RA often don’t feel well. They
may be tired or run a fever. People of any age can develop RA, and it is more common in
women.
RA can attack almost any joint in the body,
including the joints in the fingers, wrists, shoulders, elbows, hips, knees, ankles, feet, and neck. If you have RA
in a joint on one side of the body, the same joint on the other side of your body will probably have RA also. RA
not only destroys joints. It can also attack organs such as the heart, muscles, blood vessels, nervous system, and
eyes.
Gout is
one of the most painful forms of arthritis. An attack can begin when crystals of uric acid form in the
connective tissue and/or joint spaces. These deposits lead to swelling, redness, heat, pain, and stiffness in
the joint. Gout attacks often follow eating foods like shellfish, liver, dried beans, peas, anchovies, or
gravy. Using alcohol, being overweight, and certain medications may also make gout worse. In older people,
some blood pressure medicines can also increase your chance of a gout attack.
Gout is most often a problem in the big toe, but it
can affect other joints, including your ankle, elbow, knee, wrist, hand, or other toes. Swelling may cause the skin
to pull tightly around the joint and make the area red or purple and very tender. Your doctor might suggest blood
tests and x-rays. He or she might also take a sample of fluid from your joint while you are having an
attack.
Other forms of arthritis include psoriatic
arthritis (in people with the skin condition psoriasis), ankylosing spondylitis (which mostly affects the spine),
reactive arthritis (arthritis that occurs as a reaction to another illness in the body), and arthritis in the
temporomandibular joint (where the jaw joins the skull).
Warning
Signs
You might have some form of arthritis if you
have:
Lasting joint pain,
Joint
swelling,
Joint
stiffness,
Tenderness
or pain when touching a joint,
Problems
using or moving a joint normally, or
Warmth and
redness in a joint.
If any one of these symptoms lasts longer than 2
weeks, see your regular doctor or a rheumatologist. If you have a fever, feel physically ill, suddenly have a
swollen joint, or have problems using your joint, see your doctor sooner. Your health care provider will ask
questions about your symptoms and do a physical exam. He or she may take x rays or do
lab tests before suggesting a treatment
plan.
