What type of changes can be seen in CRPS type I?

Complex Regional Pain Syndrome (CRPS) type I typically presents with a variety of symptoms that reflect changes in the nervous system, particularly the autonomic nervous system, which controls involuntary bodily functions. Among the most notable characteristics of this condition are vasomotor changes. These changes can manifest as fluctuations in skin temperature, color alterations, and changes in sweating. For instance, the affected limb may appear warmer or cooler compared to the unaffected side, leading to a variety of abnormalities such as redness or paleness of the skin.

The presence of these vasomotor changes is significant as they help in differentiating CRPS from other forms of chronic pain. These symptoms can also indicate the degree of dysfunction occurring within the autonomic nervous system, which plays a crucial role in the abnormal responses seen in CRPS. Other options, such as immediate nerve damage, do not typically characterize CRPS type I, as the condition is more about a dysregulation of pain processing rather than direct nerve injury. Similarly, while bone changes can occur in prolonged stages of CRPS, they are not limited to growth alone and often include demineralization or osteopenia. The absence of symptoms would not be relevant either since CRPS is defined by the presence of significant pain
