What are the main differences between neuropathic pruritus and psychogenic pruritus? is it too complex to answer on here?

Complex, but: Research is being done. Here's a bit of info. PP may lessen during sleep, sites of itch may be less predictable, pre-existing emotional disturbances. NP more likely in those w/ other inflammatory illnesses. Sadly, you can have both - the small good news is that Tx is often the same. Sadly, it is only symptom relief and may not be total. Healthy life-style does help as can caring psychotherapy.
