Osteoarthritis Symptoms
Usually,
osteoarthritis comes on slowly. Early in the disease, joints may
ache after physical work or exercise. Osteoarthritis can occur in
any joint. Most often it occurs at the hands, knees, hips, or spine.
Hands:
Osteoarthritis of the fingers is one type of osteoarthritis that
seems to have some hereditary characteristics; that is, it runs in
families. More women than men have it, and they develop it
especially after menopause. In osteoarthritis, small, bony knobs
appear on the end joints of the fingers. They are called Heberden's
(HEB-err-denz) nodes. Similar knobs, called Bouchard's (boo-SHARDZ)
nodes, can appear on the middle joints of the fingers. Fingers can
become enlarged and gnarled, and they may ache or be stiff and numb.
The base of the thumb joint also is commonly affected by
osteoarthritis. Osteoarthritis of the hands can be helped by
medications, splints, or heat treatment.
Cartilage: The Key to Healthy Joints
Cartilage is 65 to 80 percent water. Three other components make
up the rest of cartilage tissue: collagen, proteoglycans, and
chondrocytes.
-
Collagen (KAHL-uh-jen): a fibrous protein. Collagen
is also the building block of skin, tendon, bone, and other
connective tissues.
-
Proteoglycans (PRO-tee-uh-GLY-kanz): a combination
of proteins and sugars. Strands of proteoglycans and collagen
weave together and form a mesh-like tissue. This allows
cartilage to flex and absorb physical shock.
-
Chondrocytes (KAHN-druh-sytz): cells that are found
all through the cartilage. They mainly help cartilage stay
healthy and grow. Sometimes, however, they release substances
called enzymes that destroy collagen and other proteins.
Researchers are trying to learn more about chondrocytes.

Knees:
The knees are the body's primary weight-bearing joints. For this
reason, they are among the joints most commonly affected by
osteoarthritis. They may be stiff, swollen, and painful, making it
hard to walk, climb, and get in and out of chairs and bathtubs. If
not treated, osteoarthritis in the knees can lead to disability.
Medications, weight loss, exercise, and walking aids can reduce pain
and disability. In severe cases, knee replacement surgery may be
helpful.
Hips:
Osteoarthritis in the hip can cause pain, stiffness, and severe
disability. People may feel the pain in their hips, or in their
groin, inner thigh, buttocks, or knees. Walking aids, such as canes
or walkers, can reduce stress on the hip. Osteoarthritis in the hip
may limit moving and bending. This can make daily activities such as
dressing and foot care a challenge. Walking aids, medication, and
exercise can help relieve pain and improve motion. The doctor may
recommend hip replacement if the pain is severe and not relieved by
other methods.
Spine:
Stiffness and pain in the neck or in the lower back can result from
osteoarthritis of the spine. Weakness or numbness of the arms or
legs also can result. Some people feel better when they sleep on a
firm mattress or sit using back support pillows. Others find it
helps to use heat treatments or to follow an exercise program that
strengthens the back and abdominal muscles. In severe cases, the
doctor may suggest surgery to reduce pain and help restore function.
The
Warning Signs of Osteoarthritis
-
Steady or intermittent pain in a joint
-
Stiffness in a joint after getting out of bed or sitting
for a long time
-
Swelling or tenderness in one or more joints
- A
crunching feeling or the sound of bone rubbing on bone
-
Hot, red, or tender? Probably not osteoarthritis. Check
with your doctor about other causes, such as rheumatoid
arthritis.
-
Pain? Not always. In fact, only a third of people whose x
rays show evidence of osteoarthritis report pain or other
symptoms.

Rheumatoid Arthritis
And Its Symptoms
Rheumatoid
arthritis is an inflammatory disease with symptoms that include pain, swelling,
stiffness, and loss of function in the joints. It has several
special features that make it different from other kinds of
arthritis. For example, rheumatoid arthritis generally occurs
in a symmetrical pattern, meaning that if one knee or hand is
involved, the other one also is. The disease often affects the wrist
joints and the finger joints closest to the hand. It can also affect
other parts of the body besides the joints. In addition, people with
rheumatoid arthritis may have fatigue, occasional fevers, and a
general sense of not feeling well.
Rheumatoid
arthritis affects people differently. For some people, it lasts only
a few months or a year or two and goes away without causing any
noticeable damage. Other people have mild or moderate forms of the
disease, with periods of worsening symptoms, called flares, and
periods in which they feel better, called remissions. Still others
have a severe form of the disease that is active most of the time,
lasts for many years or a lifetime, and leads to serious joint
damage and disability.

Symptoms
of Rheumatoid Arthritis
-
Tender, warm, swollen joints
-
Symmetrical pattern of affected joints
-
Joint inflammation often affecting the wrist and finger joints
closest to the hand
-
Joint inflammation sometimes affecting other joints, including
the neck, shoulders, elbows, hips, knees, ankles, and feet
-
Fatigue, occasional fevers, a general sense of not feeling
well
- Pain
and stiffness lasting for more than 30 minutes in the morning
or after a long rest
-
Symptoms that last for many years
-
Variability of symptoms among people with the disease

Although
rheumatoid arthritis can have serious effects on a person's life and
well-being, current treatment strategies--including pain-relieving
drugs and medications that slow joint damage, a balance between rest
and exercise, and patient education and support programs--allow most
people with the disease to lead active and productive lives. In
recent years, research has led to a new understanding of rheumatoid
arthritis and has increased the likelihood that, in time,
researchers will find even better ways to treat the disease.
