Outcome Measures
Primary Outcomes (1)
Neuropathic pain; 4 Questions Neuropathic Pain Questionnaire
The DN4 questionnaire (4 Questions Neuropathic Pain Questionnaire) will be used. It is a clinician-administered questionnaire. It consists of ten items. Seven items related to pain quality (i.e. sensory and pain descriptors) are based on an interview with the patient. Three items are based on the clinical examination. The clinician assesses whether there is reduced sensation (hyposthesia) to touch or pinprick and whether light brushing increases or causes pain (allodynia). All of the positive items are scored as one point and total score is sum of the scores of these positive items. The diagnosis is based on 4/10 cut-off value.

Night pain (VAS, 0-10 cm) Participants will be asked to report the pain intensity that they feel on a line between 0 and 10, higher scores indicating more intense pain.
