Jane
(* not real name) was a patient I got to know really well during
my residency training. For many years she would complain of intense
sharp pains that first started at her left wrist, gradually made
its way to shoulders and back. Over the counter pain pills didn't
seem to help, and despite numerous X-rays and CT scans, nothing
was found. It got so bad, it seemed even clothing would exacerbate
her pain. She ended up having to wear a tube top wherever she
went, which certainly caused a ruckus at home and at the workplace.
She received lecherous advances from strangers who interpreted
her less than discrete apparel as an easy come-on for sex. This
once vibrant woman, once a receptionist for a telecommunications
company, now was asked to transfer to a much less public position
as a telemarketer. Only through numerous visits with her doctor,
was the diagnosis of reflex sympathetic dystrophy (RSD) given.
Jane is now learning to cope with her disease, with a combination
of treatments, yet every day is a struggle.
Reflex sympathetic dystrophy is a controversial, often misunderstood
disease among the medical establishment. Also known as Complex
Regional Pain Syndrome (CRPS), its causes are unknown. Reflex
sympathetic dystrophy affects the sympathetic nervous system,
which controls various bodily functions, among which is our body's
temperature regulation through blood vessel constriction. Although
anyone may be affected, it is commonly seen in middle-aged women.
It often is in relation to recent trauma, although 25-30 percent
report never having had a previous injury. A similar percentage
has also been seen following a stroke or heart attack.
Usual symptoms are severe burning pain usually affecting an arm,
leg, hand, or shoulder. There is often a change in temperature
and intense sweating of the limb. The extremity may also be swollen,
and there is an intense overprotection and avoidance of the limb
by the person affected with RSD.
There have been various therapies postulating how RSD works. Many
think RSD is a result of misfiring or overactive sympathetic nerve
fibers. An abnormal response to the normal pain cycle ensues,
resulting in intractable pain. If this pain persists, it may result
in permanent disability as different components of the body become
affected. It seems to improve with nerve blocks.
There are three stages of RSD that are commonly categorized. Each
stage can vary in time with different individuals, but they are
approximately six months in duration and all involve chronic pain.
The first stage, also known as the acute stage, the affected extremity
has redness or swelling. The second stage may have a bit lessened
intensity of pain, but changes in the skin, hair, and nail are
seen. Stage three is severe function restriction, osteoporosis,
and muscle atrophy. At this last stage, it is often thought to
be irreversible.
Diagnosing treatment is often one of exclusion. Past history and
physical examination are very important components in diagnosing
RSD. Other testing may involve nerve studies, X-rays, bone and
CAT scans. A trial of a sympathetic nerve block may also aid in
elucidating the diagnosis.
Treatment has been multifocal. Although nerve blocks were commonly
used, most successful therapies employ begin with vigorous physical
therapy. To encourage more limb movement, have been found to decrease
the progression of the disease. A key component of treatment is
early recognition.
An anti-inflammatory medication such as ibuprofen has been employed.
Narcotics have proven to be of short-term benefit and not as useful.
A TENS (Transcutaneous Electrial Nerve Stimulator) is a battery-operated
device that has been tried to help block nerve impulses. Last
resort may include surgery, involving sympathetectomy.
Living with RSD is a constant struggle. Significant changes can
affect family and the workplace. Avoidance of stressful situations
is sometimes the most helpful course of action.
