Peripheral Neuropathy and neuropathic pain (burning, buzzing, electrical currents, icy sensations, etc)?

Peripheral Neuropathy has diminished reflexes whereas neuropathic pain does not??? The presence or absence of knee and ankle reflexes determines whether one has PN, as a simple rule of thumb???? I don't know, I'm just asking!

Can anyone clarify the demarcation between the two.....please?
