Imagine living every day with a constant, searing type of pain that starts in the hands and spreads to the legs. This pain may occur even without a specific cause, but it is unresponsive to any over-the-counter pain medication and persists enough to interfere with daily life. Reflex sympathetic dystrophy is just this sort of pain. Here’s what you need to know about this condition.
Reflex sympathetic dystrophy (RSD) is also referred to as complex regional pain syndrome (CRPS). These two terms are used interchangeably for the same syndrome.
Reflex sympathetic dystrophy typically occurs in the upper or lower extremities. There are two types of reflex sympathetic dystrophy:
Both CRPS 1 and CRPS 2 have as their main symptom high levels of pain. The pain is continuous and intense and usually out of proportion to the severity of the injury. Other RSD symptoms include:
People who experience CRPS may also be extra sensitive to pain, a condition known as hyperalgesia. They may also respond to non-painful stimuli with pain sensations (referred to as allodynia). These symptoms can change over time, appearing and disappearing in phases.
The cause of reflex sympathetic dystrophy is still unclear, especially when it has no known trauma or injury. Some researchers believe this condition is caused by damage to the peripheral or central nervous systems.
Another theory is that CRPS is caused by an immune response that leads to the inflammatory symptoms of redness, warmth, and swelling in the affected area.
CRPS 2 may also have its roots in traumatic injury radiation therapy, cancer, surgery, soft tissue injuries, or paralysis in the body.
It can take a long time to receive a reflex sympathetic dystrophy diagnosis, especially if there is no identifiable trauma or root cause.
There are no specific tests to diagnose CRPS. Diagnosis is a process of exclusion.
Blood testing can be done to rule out other inflammatory or rheumatologic conditions. Nerve conduction studies rule out peripheral neuropathy or nerve entrapment conditions. Your doctor might also recommend an MRI to rule out any soft tissue injury that might be causing symptoms.
A RSD diagnosis is generally made in the absence of other possible causes for your pain.
This is a very complex pain disorder that can be incredibly difficult to treat. It often begins in the hand or the foot before spreading to the affected arm or leg. Then, however, it can also spread to the opposite arm or leg.
Although treatable in the early stages, there are signs that the condition can become permanent. Once the skin begins to change, or the nails change in terms of growth, this condition may be irreversible. Early treatment is crucial.
In general, these reflex sympathetic dystrophy treatments may relieve symptoms:
If conservative or minimally-invasive treatments do not help relieve pain, spinal cord stimulation is an option. Spinal cord stimulation involves placing small electrodes within the epidural space of the spine. These small electrodes deliver a mild electrical current to the epidural space, interrupting the transmission of pain signals. The patient controls these currents directly.
