Is central sensitization the same as CRPS?

Hypothetical mechanisms. In most cases, experts believe that CRPS develops when persistent noxious stimuli from an injured body region leads to peripheral and central sensitization, whereby primary afferent nociceptive mechanisms demonstrate abnormally heightened sensation, including spontaneous pain and hyperalgesia.

What is the difference between CRPS and CPS?

CRPS is best construed as a reaction to injury, or to excessive, often iatrogenic, immobilization after injury; but it is not an independent disease. The diagnosis of CPS groups together ill-defined symptoms under a convenient, but medically untestable and therefore inept label.

What is the difference between RSD and fibromyalgia?

Fibromyalgia patients tend to have more generalized pain, earlier complaints of fatigue, and a history of immune system over-activity or persistent infection when compared to the RSD patient. Fibromyalgia patients are less likely to have an inciting event that they can relate their symptoms to.

Can an MRI detect CRPS?

MRI cannot distinguish between CRPS and non-CRPS patients. MRI’s role in CRPS is to exclude alternative diagnoses. Bone marrow edema was absent in up to 50 % of CRPS patients.

Which is worse CRPS or fibromyalgia?

However, CRPS is more intense, being marked by burning, aching pain, and exhaustion, and a highly localized area of pain. Relative to CRPS, FM is associated with less intense and generally widespread pain, and tenderness in the musculoskeletal system.

What is the difference between Hyperpathia and allodynia?

For pain evoked by stimuli that usually are not painful, the term allodynia is preferred, while hyperalgesia is more appropriately used for cases with an increased response at a normal threshold, or at an increased threshold, e.g., in patients with neuropathy.

What is the difference between allodynia and hyperalgesia?

Definition. Allodynia is pain due to a stimulus that does not normally elicit pain. Hyperalgesia is increased pain from a stimulus that normally provokes pain.
