複雜性局部疼痛症候群 1 型和 2 型（Complex Regional Pain Syndrome, CRPS）是一種發生機轉和病程不明的疼痛症候群
CRPS 有兩種類型，具有相似的體徵和症狀，但原因不同：

1 型: 也稱為反射性交感神經營養不良 (RSD)，這種類型發生在未直接損害患肢神經的疾病或受傷後。大約 90% 的 CRPS 患者屬於 1 型。
2 型: 曾經被稱為灼痛，這種類型的症狀與 1 型相似。但 2 型 CRPS 發生在明顯的神經損傷後。

關於灼痛
灼痛是一種罕見的與部分周圍神經損傷相關的疼痛綜合徵。周圍神經系統包括從大腦和脊髓的中樞神經系統延伸到服務於四肢和器官的神經。
嚴重的病例稱為大灼痛。輕微灼痛描述不太嚴重的形式，類似於反射性交感神經營養不良 (RSD)。 RSD 包括肌肉和關節疼痛症狀，以及骨密度的變化。
灼痛通常是由臂叢神經損傷引起的，涉及從頸部到手臂的神經。神經信號的中斷會導致疼痛和神經遞質去甲腎上腺素的釋放增加，從而導致血管症狀。

Complex regional pain syndrome Type 1 and Type 2（Complex Regional Pain Syndrome, CRPS）
CRPS occurs in two types, with similar signs and symptoms, but different causes:

Type 1. Also known as reflex sympathetic dystrophy (RSD), this type occurs after an illness or injury that didn’t directly damage the nerves in your affected limb. About 90% of people with CRPS have type 1.
Type 2. Once referred to as causalgia, this type has symptoms similar to those of type 1. But type 2 CRPS occurs after a distinct nerve injury.

About Causalgia General Information
Causalgia is a rare pain syndrome related to partial peripheral nerve injuries. The peripheral nervous system encompasses nerves that extend from the central nervous system of the brain and spinal cord to serve limbs and organs.
Severe cases are called major causalgia. Minor causalgia describes less severe forms, similar to reflex sympathetic dystrophy (RSD). RSD includes muscular and joint pain symptoms, and changes in bone density.
Causalgia is usually caused by brachial plexus injuries, involving nerves that run from the neck to the arm. The disruption of neural signals causes pain and increased release of the neurotransmitter norepinephrine, which causes vascular symptoms.
