CRPS type II is distinguished from type I by which feature?

The main concept is that CRPS type II, also known as causalgia, is defined by an identifiable peripheral nerve injury. In this type, there is overt damage to a peripheral nerve, and the pain and symptoms correspond to the distribution of that nerve. This contrasts with CRPS type I, where there is no confirmed nerve lesion despite similar regional pain and autonomic changes after injury. So the distinguishing feature is the presence of a known nerve injury, which is what makes CRPS type II different from type I. The other statements aren’t correct because pain after injury, involvement of autonomic changes, and involvement of limbs can occur in CRPS in general, and CRPS can affect more than just the upper limbs.
