Item	“Yes” score	“No” score	Maximal score
In the area where you have pain, do you also have “pins and needles”, tingling or prickling sensations?	5	0	5
Does the painful area change colour (perhaps look mottled or more red) when the pain is particularly bad?	5	0	5
Does your pain make the affected skin abnormally sensitive to touch? Getting unpleasant sensations or pain when lightly stroking the skin might describe this	3	0	3
Does your pain come on suddenly and in bursts for no apparent reason when you are completely still? Words like “electric shocks”, jumping and bursting might describe this	2	0	2
In the area where you have pain, does your skin feel unusually hot like a burning pain?	1	0	1
Gently rub the painful area with your index finger and then rub a non-painful area (for example, an area of skin further away or on the opposite side from the painful area). How does this rubbing feel in the painful area?	Pins and needles, tingling, electrical shock = 5	same as painful area = 0	5
Gently press on the painful area with your fingertip and then gently press in the same way onto a non-painful area (the same non-painful area that you chose in the last question). How does this feel in the painful area?	Numbness or tenderness = 3	same as painful area = 0	3
