Five components of:
1. Pain, especially mechanical and thermal allodynia, hyperalgesia and hyperpathia
2. neurogenic edema
3. autonomic dysregulation with abnormal circulation, livedo reticularis and hyperhidrosis
4. Movement disorder with inability to initiate or maintain maovements, dystonia, weakness, spasms and tremor
5. atrophy and dystrophy.

In type I there is no identifiable nerve injury, in type 2 there is. Its regional, non nerve dependent and spreads, initially is sympathetic dependent later not.
