Case report. ⋯ This case report indicates that transdermal administration of lidocaine could be potentially useful in the treatment of acute central painful neuropathies. We hypothesize that the transdermal administration of lidocaine induces suppression of ectopic impulses in sensitized cutaneous afferents, leading to some kind of 'dewinding syndrome' in the dorsal horn, which in turn leads to a decrease of painful symptoms.
