It may be associated with abnormal sensations called dysesthesia, and pain produced by normally non-painful stimuli (allodynia).<unk> c pain may have continuous and/or episodic (paroxysmal) components. The latter are likened to an electric shock. Common qualities  include burning or coldness, "pins and needles" sensations, numbness and itching.
