Primary Outcome Measures

Name	Time	Method
Dermal pain [LEVEL OF PAIN]	1 month	Questionnaire. Visual Analogue Scale (VAS). Patients will be asked to report on their average and maximum level of pain on a scale from 0-10.

Secondary Outcome Measures

Name	Time	Method
Neuropathic pain [LEVEL OF PAIN]	1 month	Neuropathic Pain Symptom inventory (NPSI), Questionnaire. NPSI consists of 12 items in total: 10 items investigates differential symptoms descriptors and 2 items evaluate spontaneous and paroxysmal spontaneous pain.; The tool evaluates mean pain intensity in the last 24h in a verbal numeric scale from zero (no pain) to 10 (worst imaginable pain). Total pain intensity score may be calculated by the sum of the 10 descriptors.; The descriptors are: Burning, Squeezing, Pressure, Electric Shocks, Stabbing, Provoked by brushing. Provoked by pressure, Evoked by cold stimulation, Pins and needles, Tingling.
Quality of life [QUALITY OF LIFE/ SATISFACTION]	1 month	Short Form 36 (SF-36), Questionnaire. Scoring the RAND 36-Item Health Survey is a two-step process. First, precoded numeric values are recoded per a scoring key. All items are scored so that a high score defines a more favorable health state. Each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively. Scores represent the percentage of total possible score achieved. After this, items in the same scale are averaged together to create the 8 scale scores.; The eight health concepts are: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. It also includes a single item that provides an indication of perceived change in health.
