Nerve Pain

Hi my name is Ken, really pleased to find this site and this forum. The helpline has also been a boon so a big thank you to everyone involved I have had psoriasis for a few years now, have recently gone through quite an outbreak of plaque. i have a new symptom which I can only describe as a severe nerve pain. It occurs from the lightest touch on a specific patch (lower leg) and results in shooting/electric like pains radiating both upwards and downwards. I am generally pretty good with pain but this is quite shocking, probably due to the suddenness of it. My GP has referred me for X-Ray but cannot offer any other thoughts at the moment. Has anyone experienced a similar thing and if so did you find a solution to managing it?
